Question 651433
First, notice we can factor out a -2x out of the equation.

{{{-2x^3+2x^2+4x = -2x(x^2 -x -2) = 0}}}

Now we have x^2-x-2, a quadratic.

Notice that we have two integers that add up to -1 and multiply to -2, namely -2 and 1.

Then we have {{{-2x(x-2)(x+1)}}} which is our factored form.

Hope this helps!
