Review the chapter on "Factoring" to refresh your memory if you don't quite remember how to factor polynomials. It will definitely help you solve the questions in this lesson!

Basic Concepts:Factoring polynomials: $ax^2 + bx + c$, Factoring perfect square trinomials: $(a + b)^2 = a^2 + 2ab + b^2$ or $(a - b)^2 = a^2 - 2ab + b^2$, Find the difference of squares: $(a - b)(a + b) = (a^2 - b^2)$, Solving polynomial equations,

Basic Concepts:System of linear-quadratic equations, System of quadratic-quadratic equations, Graphing quadratic inequalities in two variables,

Difference of Squares: $a^2-b^2=(a+b)(a-b)$
