Question 84814
Factor the expression (it's not an equation, no equals sign):
{{{-12x^3+36x^2}}} First, look for common factors in each term.
{{{(-12x^2)(x) + (12x^2)(3)}}} So you can factor out a -12x^2.
{{{-12x^2(x-3)}}} Notice the change in the sign of the second term.
Now the first factor {{{-12x^2}}} itself can be factored:
{{{-12x^2 = -3(4x^2)}}} Notice that the {{{4x^2}}} can also be factored:
{{{4x^2 = (2x)(2x)}}}. So...putting it all together, we have:
{{{-12x^3+36x^2 = -3(2x)(2x)(x-3)}}}
