More Chain Rule (NancyPi)

If someone sees this what happens to the power of 4 in this step: 8x^3(2x-5)^3+3x^2(2x-5)^4, I get how x^2 was a common factor leading to [8x+3(2x-5)] but why Is (2x-5) no longer raised to the power of 4

[@fly4doe2]

I'm with you. Didn't quite get that last simplification. Nor did she refer us to another one of her vids. I guess it is just basic algebra and so we are SOL.

[@eg8charles]

Hi Lalo .g17 and fly4doe, just like x^2 being a common factor so is (2x-5). In fact you could factor up to (2x-5)^3 from both terms. It will leave this.. y'= x^2(2x-5)^3
