Best Answer

To find the original number when given the prime factors, we have to work backwards.

First, we simplify into 2 squared times 3 squared.

(2x2) x (3x3)

Then we expand the brackets.

4 x 9 = 54

Therefore 54 is the number, with 2x2 and 3x3 as the prime factors.

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
