Supposing that this is the case, we can then find the other factor using long division: Since the remainder after dividing is zero, this shows that is indeed a factor and that the correct factoring is.

Similarly, the sum of two cubes can be written as. Finding factors sums and differences. In the previous example, we demonstrated how a cubic equation that is the difference of two cubes can be factored using the formula with relative ease. Example 5: Evaluating an Expression Given the Sum of Two Cubes. We might wonder whether a similar kind of technique exists for cubic expressions. This factoring of the difference of two squares can be verified by expanding the parentheses on the right-hand side of the equation. So, if we take its cube root, we find. We note, however, that a cubic equation does not need to be in this exact form to be factored. Regardless, observe that the "longer" polynomial in the factorization is simply a binomial theorem expansion of the binomial, except for the fact that the coefficient on each of the terms is.
Sum Of Factors Equal To Number
Note, of course, that some of the signs simply change when we have sum of powers instead of difference. A simple algorithm that is described to find the sum of the factors is using prime factorization. Thus, we can apply the following sum and difference formulas: Thus, we let and and we obtain the full factoring of the expression: For our final example, we will consider how the formula for the sum of cubes can be used to solve an algebraic problem. The sum or difference of two cubes can be factored into a product of a binomial times a trinomial.

In other words, is there a formula that allows us to factor? We note that as and can be any two numbers, this is a formula that applies to any expression that is a difference of two cubes. Review 2: Finding Factors, Sums, and Differences _ - Gauthmath. Suppose, for instance, we took in the formula for the factoring of the difference of two cubes.
Finding Factors Sums And Differences
In order for this expression to be equal to, the terms in the middle must cancel out. I made some mistake in calculation. This can be quite useful in problems that might have a sum of powers expression as well as an application of the binomial theorem. Sum of factors equal to number. In this explainer, we will learn how to factor the sum and the difference of two cubes. Enjoy live Q&A or pic answer. If we expand the parentheses on the right-hand side of the equation, we find. This leads to the following definition, which is analogous to the one from before.
Since the given equation is, we can see that if we take and, it is of the desired form. This is because each of and is a product of a perfect cube number (i. e., and) and a cubed variable ( and). Using substitutions (e. g., or), we can use the above formulas to factor various cubic expressions. Are you scared of trigonometry? Rewrite in factored form.
What Is The Sum Of The Factors

Therefore, we can confirm that satisfies the equation. To show how this answer comes about, let us examine what would normally happen if we tried to expand the parentheses. One way is to expand the parentheses on the right-hand side of the equation and find what value of satisfies both sides. Gauthmath helper for Chrome.

We can find the factors as follows.
An alternate way is to recognize that the expression on the left is the difference of two cubes, since. Factor the expression. Therefore, it can be factored as follows: From here, we can see that the expression inside the parentheses is a difference of cubes. Specifically, we have the following definition.
Still have questions? This allows us to use the formula for factoring the difference of cubes. However, it is possible to express this factor in terms of the expressions we have been given. Note that we have been given the value of but not.
Let us continue our investigation of expressions that are not evidently the sum or difference of cubes by considering a polynomial expression with sixth-order terms and seeing how we can combine different formulas to get the solution.
