WebExplanation of the Formula -- Using the Sum of Cubes. On the page about the sum of cubes we showed that a 3 + b 3 = a 2 − a b + b 2. We can use this formula to find a factorization …
WebOn the other hand, 2x 2 − 162 = 2(x 2 − 81), and x 2 − 81 is a quadratic. When you see that you have a two-term non-linear polynomial, check to see if it fits any of the formulas. In this case, you've got a difference of squares, so apply that formula: 2x 2 − 162 = 2(x 2 − 81) = 2(x − 9)(x + 9). Warning: Always remember that, in cases like 2x 2 + 162, all you can do is … WebDec 13, 2009 · Factor a sum or difference of cubes. Apply the factoring strategy to factor a polynomial completely. Introduction Factoring is to write an expression as a product of factors. For example, we can write 10 as (5) (2), where 5 and 2 are called factors of 10. We can also do this with polynomial expressions.
WebTo factor a difference of cubes, we can follow the following steps: Step 1: Decide if the two terms have a common factor, called the greatest common factor. If so, we factor the …
WebA polynomial in the form a 3 + b 3 is called a sum of cubes. A polynomial in the form a 3 – b 3 is called a difference of cubes.
