int((5x^(2)-12)dx)/((x^(2)-6x+13)^(2))

int (x^(2)dx)/(x^(2)+6x+12)

If f(x)=int_(1)^(x^(3))(dt)/(1+t^(4)), then f'(x) is equal (6x((1-5x^(2))^(12)))/((1+x^(12))^(12))) (ii) (6x((1+5x^(2))^(12)))/((1+x^(12))^(2))( (iii) -(6x((1-5x^(2))^(12)))/((1+x^(12))^(2)) (iv) none of these

int ((x+2)dx)/(2x^(2)+6x+5)

int (x^(2)dx)/(x^(6)-5x^(3)+6)

int(x^(2))/(x^(2)+6x+12)dx

int(x^(2))/(x^(2)+6x-12)dx

int(x^(2))/(x^(2)-5x+6)dx=

int(x^2)/(x^2+6x-12)dx

int(1)/(6+5x-6x^(2))dx

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