used with rational functions -r(X)=p(X)/q(X) -degree of p(X) < degree of q(X) A linear gets A during distribution A non linear gets Ax+B during distribution
3
Linear, non repeating _____________ = A + B + C (x-a)(x-b)(x-c) (x-a) (x-b) (x-c) Linear, repeating __________ = A + B + C (x-a) 2 (x-b) (x-a) (x-a) 2 (x-b)
4
Non linear, non repeating _______________ = A + Bx+C (x-a)(bx 2 +cx+d) (x-a) (bx 2 +cx+d) Non linear, repeating ________________ = (x-a)(bx 2 +cx+d) 2 A + Bx+C + Dx+E (x-a) (bx 2 +cx+d) (bx 2 +cx+d) 2
5
Factor denominator completely Separate each factor as its own denominator Determine whether each is linear or nonlinear The ones that are liner (non-repeating) get a single letter in the numerator. The ones that are non linear get two letters, one having a variable attached Solve for the numerator
