    I will use "Int" for the Integral sign..

    1. Int [ (x^2 + 6x - 5) dx = (x^3)/3 + 6(x^2/2) - 5x = (x^3)/3 + 3(x^2) - 5x

    2. Int [ {(1/x)+(1/x^2)} dx = ln x + {x^(-2+1)} / (-2+1) = ln x -(1/x) where ln is the Natural Logaritm function.

    3. Int [ 6*sqrt(x) dx ] = 6* x^{ (1/2) + 1}/^{ (1/2) + 1} = 4*x^(3/2)
