Question

factor if possible -32x^3 +72x^2 +20x

Answer 1

u should first factor out an 4x and it'll make it much easier

Answer 2

or better yet..factor out a -4x...you should get -4x(8x^2-18x-5x)

Answer 3

can you factor it from there?

Answer 4

ok for this ... let's factor out the -4x first. so we get the follwing ...

-4x ( 8x^2 - 18x - 5)

exactly like you did before.

now let's try to factor out the bracket.

the bracket can be factored out to the following:

(2x -5 ) ( 4x + 1)

so final answer is -4x(2x-5)(4x+1)
