4a2 + 4ab - y2 + b2

You cannot simplify this expression because it does not contain like terms, but you can factor it such as:

4a2 + 4ab - y2 + b2

= (4a2 + 4ab + b2) - y2

= (2a + b)2 - y2

= [(2a + b) - y][(2a + b) + y]

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
