Hey guys, i have no answers to these but would like to know if I have got them right.

Integral x(3x^2+1)^4 = 1/30(3x^2+1)^5

Integral x^2(2-x^3) = -6(2-x^3)^2

Integral 2x(x^2-5)^3 = 1/4(x^2-5)^4

Thankyouu

You got one wrong.

Differentiate them yourself.

I will change the bottom one to 16(x^2-5)^4

That one was correct previously.

Spoiler:

Edit: It's the second one that's in error.

Hmm i don't see how it's wrong :/

What do you get when you differentiate the RHS of the second one then?
