Ok, so heres the problem, it asks me to simplify the expression:

{(2x-1)^4 * 3(x+3)^2 - 4(2x-1)^3 * 2(x+3)^3} / (2x-1)^8

I was thinking of using binomial therom since it looks like theres gonna be a lot of mulitplying

heres what i tried:

{(16x4+-32x3+24x2+-8x) * 3(1x2+6x1+9) - 4(8x3+-12x2+6x+-1) * 2(1x3+9x2+27x+27)} / (256x8+-1024x7+1792x6+-1792x5+1120x4+-448x3+112x2+-16x)
