Suppose that f is a polynomial and h is a polynomial of degree 5 or less such that

\((x^2+3x-3)\cdot f(x)+h(x)= -6x^6+72x^4 -50x^3 + 13x^2 +38x -44\)

What is the degree of f?


please help...

If h is degree 5 or less    the terms from adding it all have exponents 5 or less

 

f(x) is multiplied by a polynomial of degree 2

    the right side has a term of degree 6      so f(x) must be of degree 4

           example    x^2  * f(x)

                             x^2 * x^4   = x^6
