Write the problemThe binomial should be expressed in parentheses to denote multiplication.Multiply the first two binomials to produce a trinomialFor an example problem, cube the binomial (x - 3). Write it as (x - 3)(x - 3)(x - 3). Multiply the first x by x, then by -3. Then, multiply -3 by x and by -3. Combine like terms. This yields the term (x^2 - 6x + 9).Multiply the trinomial by the binomial.The example now should appear as (x^2 - 6x + 9)(x - 3). For convenience, it can be rewritten the other way around. Now, multiply the first term by each of the other terms in the other expression in seq..

Two-dimensional shapes take up area but not volume. Geometric two-dimensional shapes have straight or curved edges that require tools, such as a straight edge or compass, to draw properly. These include triangles, squares, rectangles and circles. Organic two-dimensional shapes are formed of irregular lines. The qualities of geometric two-dimensional shapes are studied in the discipline of plane geometry. Although objects are sometimes portrayed by two-dimensional shapes, all real-world objects have some depth and take up volume, making them three-dimensional.

To find the prime factorials for any number divide the number by the smallest prime possible, then divide the result by the smallest prime, and continue this process until the result is a prime number. The primes that were used to divide and the result are the set of prime factorials. For example 68 divided by 2 is 34. Then 34 divided by 2 is 17. Since 17 is a prime number 2, 2 and 17 are the prime factorials of 68.

A prime number is a positive integer greater than 1 that are only divisible by 1 and itself, without giving off a remainder. The prime factorization of any number is determined by writing down all prime numbers that are used to reduce the value to its simplest form.To obtain the prime factorization of 375, it is initially divided by 3, which is the smallest prime number that evenly divides it. The resulting value of 125 is again divided by 5 to give 25. The number 25 is further divided by 5 to get 5. Since 5 is no longer divisible by any other prime number, the prime factorization for 375 is 3..
How do you round decimal numbers?

If the place you have chosen to round to has a value of nine and must be rounded up, it becomes a zero, and the value of the preceding digit increases by one. For instance, 1.795 rounded to the nearest hundredth becomes 1.80; additionally, 1.9995 rounded to the nearest thousandth becomes 2.000.\nWhen rounding a decimal to the right of the decimal point, no zeros need to be added; for instance, 123.456 rounded to the nearest tenth becomes 123.5. However, when rounding to the left of the decimal point, zeros must be used as placeholders for any digits dropped by rounding on the left side of the ..

First, consider baking a marble cake. Any cake recipe calls for various exact measurements. Failure to adhere to a recipe's specification to use 1/2 teaspoon of salt, for instance, could ruin the entire cake. Without mathematics, measurement systems would not exist. Therefore, in a world without mathematics, a baker hoping to make a marble cake in precisely the same way she made the marble cake the week before would have a difficult task ahead of her.\nReplacing living room carpet requires mathematics. Mathematics are needed to determine the dimensions of the living room, to calculate the..
What happens when you increase the number of classes in a histogram?

A histogram is a method for data visualization in which data frequency, or counts, are plotted against data value. For instance, if a data set has eight data points falling in the range 3 - 5, a bar spanning the data range 3 - 5 would be plotted, with a height of 8 units. The number of classes controls how wide the data ranges are. Increasing the number of classes will shrink the data ranges, for instance from 3 - 5 to 3.8 - 4.2.\nHistograms are useful for getting an overall picture of the data set and its features. They are particularly useful for quickly identifying skewness, modality and..

The lines of longitude on a map all intersect with each other at the North Pole and South Pole. They run up and down from the two poles around the globe. Coordinates are measured and read in terms of degrees latitude and longitude. Zero degrees for latitude is the Equator, while zero degrees for longitude is the Prime Meridian.
How do you find the slope of a line passing through two points?

The equation for calculating the magnitude of the slope, where m is the slope of a line with x and y coordinates and ? is change, is m=?y/?x. To apply this formula, pick any two points on the line, and determine their x and y coordinates. The x value indicates the point's position on the horizontal axis; y is its position on the vertical axis. Subtract the y-coordinate of the first point from the y coordinate of the second point. Then, subtract the x-coordinate of the first point from the x-coordinate of the second point. Divide the difference in y-coordinates by the difference in x-coord..

Positive integers are the numbers used when counting. Every positive integer has 1 and itself as factors. This is because 1 times any number gives that number as a result. More factors are found by dividing the number by 2 and then 3, working through the integers in succession. Whenever the answer to the division problem is a positive integer, the two numbers are factors of the original number. For example, when 78 is divided by 6 the answer is 13, so 6 and 13 are factors of 78. On the other hand, 78 divided by 8 equals 9.75. That is not a positive integer, so 8 is not a factor of 78. When wor..
