Question

When completely factored, 2x3 - 200x
equals-

Answer 1

Explanation:

The only way this can be factored is by pulling out the GCF. 2 and x are common to both terms:

`2x(x^2-100)`

BUT you should also recognize that what's inside the parenthesis is the difference of perfect squares. And that factors to

(x - 10)(x + 10). So the complete factorization is

2x(x - 10)(x + 10)
