Integration by Partial Fractions
people.math.sc.eduThere is no indicator of what the numerators should be, so there is work to be done to find them. If we let the numerators be variables, we can use algebra to solve. That is, we want to find constants A and B that make the equation below true for all x 6= −5,−2. x +14 (x +5)(x +2) = A x +5 + B x +2. We solve for A and B by cross ...
