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

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

int(dx)/(x-x^(2)-2.5)

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

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

int(dx)/(2x^2+3x+5)=

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

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

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