I am having trouble with the following question:
Complete the square in the quadratic expression q which is given by
q=16x^2+32x+17
and use this to evaluate the following integral
int(1/sqrt(16x^2+32x+17)dx)
(the integral of one over the square root of (16x^2+32x+17))
This is just way over my head...
I tried to solve 16x^2+32x+17=0, and I got
x1= -1 + 0.25*i
x2= -1 - 0.25*i
which wasn't very helpful.
q can also be rewritten as (x + 1)(x + 1) + 0.0625, but again, I don't know where to go from here...
And help would be greatly appreciated
