Question

evaluate using the substitution method:
(x^6-2x^5)^6(6x^5-10x^4)dx

a. 1/7(x^6-2x^5)^7+C
b. (x^6-2x^5)^7+C
c. 6x^5-10x^4+C
d. 1/6(x^6-2x^5)^6+C

Answer 1

let u=x^6-2x^5
so du=(6x^5-10x^4)dx

your integral is now just integral [u^6] du

Answer 2

can u take it from here?

Answer 3

got an answer yet?

Answer 4

i got D...?

Answer 5
