To solve this integral you should use the integration by parts formula, which is uv - integral of vu'. First let x^2 be u, therefore u'(the differential of x^2) = 2x, v' = e^x and therefore v (integral of...

Use the moon method.

E.g. (x+1)(x+2) 

1. multiply x with x

2. multiply x with 2

3. mutiply 1 with x

4. multiply 1 with 2
