(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

y =x^{4}(2x-5)^{6}

2. Relevant equations

Product Rule & Power of a Function Rule

3. The attempt at a solution

y = x^{4}(2x-5)^{6}

y' = 4(x)^{3}(1)(2x-5)^{6}+ x^{4}(6)(2x-5)^{5}(2)

y' = 4x^{3}(2x-5)^{6}+ 12x^{4}(2x-5)^{5}

The answer is:

20x^{3}(2x-5)^{5}(x-1)

No idea where they get the 20x^{3}or the (x-1). If I were to factor my answer, I still wouldn't get that, I think.
