How do you integrate #int (3x + 2) / [(x - 1)(x + 4)] # using partial fractions? Calculus Techniques of Integration Integral by Partial Fractions 1 Answer Konstantinos Michailidis Feb 21, 2016 We have that #(3x+2)/[(x-1)(x+4)]=2/(x+4)+1/(x-1)# Hence #int (3x+2)/[(x-1)(x+4)]dx=int 2/(x+4)dx+int 1/(x-1)dx= 2*logabs(x+4)+logabs(x-1)+c# Answer link Related questions How do I find the partial fraction decomposition of #(2x)/((x+3)(3x+1))# ?
