Answer:
There are two ways to factorize x2−16 - one using identity a2−b2=(a+b)(a−b) . Other method is by splitting the middle term, which is 0 here and as product of coefficient of x2 and constant term is −16 . we need to do is to split middle term in 4 and −4 (as their sum is zero and product is −16 )
Step-by-step explanation:
Multiply the number and variable together to get 2x. Then divide each part of the expression by 2x. The expression with the GCF factored out is 2x (x^2 + 9x + 5). Note that you must put the factored expression in parentheses and write the GCF next to it.
