`int(x^(2)+4x+6)dx`

int(x+2)(2x+6)dx

Evaluate I=int 1/(3x^2+4x+6)dx

Evaluate: int(x^(2)+4x)/(x^(3)+6x^(2)+5)dx

(i) int((x^(2) - 1)/(x^(2) + 1))dx , (ii) int ((x^(6)- 1)/(x^(2) + 1))dx (iii) int ((x^(4))/(1+x^(2)))dx , (iv) int((x^(2))/(1+x^(2)))dx

int6x e^(x^(2))dx=

Evaluate: int(2x+3)sqrt(4x^(2)+5x+6)dx

int(x+2)/(sqrt(x^(2)+4x+3))dx

int (6x^(2)-(4)/(x^(2))) dx

int(x^(3)-4x^(2)+x-6)/(x^(2))dx
