2x4 - 9x3 + 13x2 - 15x + 9

= 2x4 - 6x3 - 3x3 + 9x2 + 4x2 - 12x - 3x + 9

= 2x3(x - 3) - 3x2(x - 3) + 4x(x - 3) - 3(x - 3)

= (x - 3)*(2x3 - 3x2 + 4x - 3)

So the quotient is (2x3 - 3x2 + 4x - 3)

and the remainder is 0.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
