How do you integrate #int(x)/((x+4)(x+6)(x+1))# using partial fractions? Calculus Techniques of Integration Integral by Partial Fractions 1 Answer Leland Adriano Alejandro Jan 15, 2016 #2/3 ln (x+4) -3/5 ln (x+6) -1/15 ln (x+1)+C# C=the constant of inegration Explanation: #x=A(x^2+7x+6)+B(x^2+5x+4)+C(x^2+10x+24)# #A=2/3# #B=-3/5# #C=-1/15# #int x/((x+4)(x+6)(x+1)) dx = int A/(x+4) dx+ int B/(x+6) dx+int C/(x+1) dx# Answer link Related questions How do I find the partial fraction decomposition of #(2x)/((x+3)(3x+1))# ?
