Question

Complete the algebra to show that the function f(x)=(2(2x-3)(2)(4x+5)^3-(2x-3)^2(3)(4x+5)^2(4))/(4x+5)^6 simplifies to (-8(2x-3)(x-7))/(4x+5)^4

Answer 1

I have to say... this expression doesn't make a lot of sense...

there are 2 common factors in the numerator that can be removed

(4x + 5)^2 and (2x -3)

but some terms don't make a lot of sense..

the last 4 in the numerator... for example.
