Question Number 78075 by Rio Michael last updated on 14/Jan/20
expressing P(x) = ((x^2 + x)/((x−3)(x^2 −2))) in partial fractions gives A. (A/((x−3))) + ((Bx + C)/((x^2 −2))) B. (A/(x−3)) + (B/(x−2)) + (C/(x+2)) C. (A/(x−3)) + (B/(x−(√2))) + (C/(x + (√2))) D. ((Ax + B)/(x−3)) + (C/(x^2 −2))
expressingP(x)=x2+x(x−3)(x2−2)inpartialfractionsgivesA.A(x−3)+Bx+C(x2−2)B.Ax−3+Bx−2+Cx+2C.Ax−3+Bx−2+Cx+2D.Ax+Bx−3+Cx2−2
