Answer 1

\[\int\limits_{0}^{1}\left( z ^{2}+1 \right)^{2}dz\]

you could just expand it out right?

Answer 3

Yeah, expand it out and integrate the terms one by one.

Answer 4

I have to learn this my self for now so i have no idea what you mean by expand

Answer 5

(z^2 + 1) (z^2 + 1)

Answer 6

What's (x+1)^2? Expand the binomial to z^4 + 2z^2 + 1

Answer 7

that parts just algebra

Answer 8

i see now

Answer 9

\[\int\limits_{0}^{1} (z^2 + 1)^2 dz = \int\limits_{0}^{1} (z^4 + 2z^2 + 1) dz\]
