Question

Please help me, I do not understand how to factor out 2x^2+4x-2x^3.

Answer 1

look at it:

what do all of them have? 2x
so, I take out the 2x
2x(x+2-x^2)
or -2x(x^2-x-2)
...-2x(x-__)(x+__)
-note: I have a negative and a positive because I want a negative x
-try filling in the blank with either -2 and 1 OR 2 and -1
-which one will give me x^2-x-2?
