" 3.Find "(a)int(dx)/(2x^(2)+3x+5)

Find int(x+3)/(x^(2)-2x-5)dx .

Find : int(5x-2)/(1+2x+3x^2)dx.

Find int(dx)/(x^(2)-a^(2)) and hence Evaluate int(dx)/(3x^(2)+13x-10) Given int(dx)/(x^(2)-a^(2)) (Multiply and divide by 2a)

Find the following integrals : (i) int(dx)/(x^(2)-6x+13)int(dx)/(3x^(2)+13x-10)int(dx)/(sqrt(5x^(2)-2x))

" Evaluate ":int(x+3)/(x^(2)-2x-5)dx

Find int (3x-5)/(x (x^(2)+2x+4))dx.

Evaluate : (i) int(2x)/((2x+1)^(2))dx (ii) int((2+3x))/((3-2x))dx
