`int(7x+6)/(2x+1)dx=?`

int(7x-6)^5dx

int(4x+6)/(x^2+3x-7)dx=?

int(x^(6))/(x^(2)+1)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

int(6)/((1-2x)^(3))dx

int1/(7x+5)dx

6. int(1-x^2)/(x-2x^3)dx

int(dx)/(x+x^(7))=p(x), then int(x^(6))/(x+x^(7))dx is

int(7x+1)/((x+1)(x-2)(x-3))dx

7. int(3)/(x^(2)+2x+1)dx
