I dont know how to perform partial fraction decomposition to get the answer on the bottom

find the following integrals c] [ 3 x + 3 dx x2 - x = 13 (x+1) dx X(X - 1 ) = 3 ( x+1 + ( x - 1) dx = A, axtb (ax xb ) n = = + X X - 1 3x+3 = A(x) + B(x-1 ) plugin x = - 1:32-1)+ 3 = A(-1)+ B(- 1-1) 0 = - 1At-2B -S ( *- 1 - X ) dx
