Im having trouble solving these intergrals...if anyone can help thatd be great,

Compute the integral from -1 to 3 of the square root of (6-2x^2+4x) dx..

Also, evaluate the indefinate integral of dx / square root of (1-x^2+2x)

I know where to start, but i keep getting stuck where i have to take the antiderivative of ax^-1..which would be x^0 which doesnt make sence...

Thanks in advance
