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

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

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

The value of int (x dx)/(x^(2)+4x+5) is equal to -

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

int(x dx)/(x^(2)+4x+5) is equal to

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

int ( x +2)/( 2x ^(2) + 6x + 5) dx = p int ( 4x +6)/( 2x ^(2) + 6x +5) dx + (1)/(2) int (1)/( 2x ^(2) + 6x + 5) dx then p

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

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