Could someone please help me with this?
Is it possible to subtract two polynomials, each of degree 3, and have the difference be a polynomial of degree 2? If so, give an example. If not, explain why not.
thanks

(x^3+ 5x^2+4)  (x^3  3x^2  6x)
= x^3 + 5x^2 + 4  x^3 + 3x^2 + 6x
= 8x^2 + 6x + 4
mmmhhh?
