## qasaali 3 years ago integrate (2x^3-1)^2(6x^2)

1. lgbasallote

let u = 2x^3 - 1 du = 6x^2 so therefore the integral just becomes $\int u^2 du$ does that help?

2. qasaali

hey continue it dont stop u r on the right track

3. lgbasallote

that's already an easy integral...do you still need help?

24x^8-24x^5+6x^2

$(2x^3-1)^2(6x^2$

i simple way is just to expand it all out into a single polynomial and integrate it term for term

7. amistre64

but if method is "defined", then lgbas is prolly best

true so in this question you can say $49 * 12x$
