Factor the quadratic - 16x^2+32x

-16x (x-2)

To factor anything, let's see what they both have or they can divide by.

Oh in this equation, we see they both have x and they can divide by - 16. so factor out - 16x. - 16x (?+?), then take the numbers and symbol divide for the factor. - 16x^2/-16x = x and 32x/-16x = - 2

So we got - 16x (x-2)
