The question :-

17a) Differentiate y=x^2 (x-5)^4

17b) Differentiate y = (1-2x) (3x+4)^5

**Here’s the working to answer the question 17 a)**

**Working for 17b**

And if you’re still unclear of the Working above, then view the video tutorial below to learn my step-by-step explanation

Can you explain to me in question 17.a) how this answer 4x^2(x-5)^3+2x(x-5)^4 can be (2x)(x-9)^3(2x+x-5)??
