Question

Integrate (-2x-2)e^x

Answer 1

split this into two integrals:
-2*Integral(x*e^x)-2*Integral(e^x)
for the first integral use integration by parts.

Answer 2

That integration by parts! That's what wolfram suggested...how does it work?

Answer 3

:(

Answer 4

let u=x, du=dx, dv=e^xdx, v=e^x

Answer 5

The integral becomes:
u*v-Int(v*du)=x*e^x-Integral(e^x*dx)

Answer 6

ok
thanks.

Answer 7

you can int by parts without expanding first as well .. but potato potato ...
