    Difference of Squares Pattern
    If \(a\) and \(b\) are real numbers,

    This image shows the difference of two squares formula, a squared – b squared = (a – b)(a + b). Also, the squares are labeled, a squared and b squared. The difference is shown between the two terms. Finally, the factoring (a – b)(a + b) are labeled as conjugates.
    Factoring
    Factoring is splitting a product into factors; in other words, it is the reverse process of multiplying.
    Greatest Common Factor
    The greatest common factor is the largest expression that is a factor of two or more expressions is the greatest common factor (GCF).
    Perfect Square Trinomials Pattern
    If \(a\) and \(b\) are real numbers,

    \[a^2 + 2ab + b^2= (a + b)^2 \qquad a^2 - 2ab + b^2 = (a - b)^2\]

    Prime Polynomials
    Polynomials that cannot be factored are prime polynomials.
    Quadratic Equations
    are equations in which the variable is squared.
    Sum and Difference of Cubes Pattern
     

    \[a^3 + b^3 = (a + b)(a^2 - ab + b^2)\]

    \[a^3 - b^3 = (a - b)(a^2 + ab + b^2)\]

    Zero Product Property
    The Zero Product Property states that, if the product of two quantities is zero, at least one of the quantities is zero.
