Problem Statement
Let and be two monic polynomials of degree= having complex coefficients.
We know that there exist complex numbers , such that
f(x)\minus{}g(y)\equal{}\prod_{i\equal{}1}^n{(a_ix\plus{}b_iy\plus{}c_i)}.
Prove that there exists such that
f(x)\equal{}(x\plus{}a)^n\plus{}c\text{ and }g(y)\equal{}(y\plus{}b)^n\plus{}c.
