expanding the RHS yields the quadratic terms

note the coefficient of on the LHS is 1 , hence by matching coefficients - January 5th 2013, 03:20 PMDevenoRe: matching the terms in partial fractions
u

^{2}= (1)(u^{2}), that is, in the polynomial u^{2}, the coefficient of u^{2}is 1 (this is usually suppressed when we write polynomials). - January 5th 2013, 03:56 PMcxz7410123Re: matching the terms in partial fractions
Thank you very much.

Your answer rises me an other problem, why in the second scan there is this "0" and not 3?.
