` "int(4x+5)/(x^(2)+x-2)dx`

int(x+1)/(x^(2)+4x-5)dx

int(x+1)/(x^(2)+4x+5)dx

int(x)/(x^(2)+4x+5)dx

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

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

If int(x+2)/(2x^(2)+6x+5)dx =P int(4x+6)/(2x^(2)+6x+5)dx+(1)/(2) int (dx)/(2x^(2)+6x+5') Then the value of P is

int(1)/(x^(2)(4x+5))dx=

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

int(dx)/(x^2+4x-5)=

Evaluate: int(x+1)/(x^(2)+4x+5)dx
