Hello, please if you can help with the attached question. Thank you ever so much.

Your answer is correct, all the book has done is simply taken out a factor of (1+3x)^4.

So

15x(1+3x^4) + (1+3x)^5 = (1+3x)^4 \left(15x + (1+3x)\right) = (1+3x)^4\left(18x + 1\right)

.

Can you see what I'm getting at? Each term has a factor of

(1+3x)^4

, the first term is that multiplied by 15x and the last is that times (1+3x).

Psychology and English. C4 is alright as is D1, but C3 is just a no no.

How much revision has everyone been doing for C3? Personally I'm absolutely terrified and I don't know how I'm going to achieve 90UMS 😓😫
