Question

∫[-a,9] [x^2+x]

Answer 1

First, find the indefinite integral of x^2+x

Answer 2

Remember, ∫ ax^n dx=(a/n+1)*x^(n+1)

Answer 3

how do i find the indefinite integral?

Answer 4

∫ ax^n dx=(a/n+1)*x^(n+1)

Answer 5

∫f(x)+g(x) dx=∫f(x) dx+∫ g(x) dx

Answer 6

Then,\[\int\limits_{a}^{b}f(x)dx=F(b)-F(a)\]

Answer 7

so i do (9^2+9)-((-a)^2-a)??

Answer 8

No, you must first find the indefinite integral.

Answer 9

sorry i am so confused about how to find the indefinite integral
