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

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

    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)
