How do I input the integral?

int((x-m^2)/(x+1),x=0..m^2).

Please help me. Thank you.

Problem. Let MNPQ be a square.  Find the other two vertices,  knowing that,  the vertices M(5; 3; -1), P(2; 3; -4) and N lies on the plane x + y - z  - 6 = 0.

This is my code

with(LinearAlgebra):

M:=<5,3,-1>:

P:=<2,3,-4>:

N:=<x,y,z>:

A:=DotProduct(M-N,P-N,conjugate =false):

Problem. Find the coordinates of the point M on the sphere (S): x^2 + y^2 + z^2-2*x+4*y+2*z-3=0 such that the distance from the point M
