Factoring quadratic equations is a key algebraic skill that simplifies expressions and solves for roots. Techniques like the greatest common factor (GCF), grouping, and perfect square methods are discussed. These methods help identify binomials that reconstruct the original quadratic expression and find the points where the graph intersects the x-axis.

Factoring is a fundamental algebraic process used to simplify quadratic equations
Greatest Common Factor (GCF) Method
The GCF method involves identifying the largest factor that divides all terms of the quadratic expression
Factoring by Grouping
Factoring by grouping is effective when the leading coefficient is not one
Perfect Square Method
The perfect square method is a factoring technique for quadratic equations that are perfect square trinomials
Factoring is a vital algebraic skill for solving quadratic equations and deepening understanding of quadratic functions and their properties
Quadratic equations are equations that can be written in the form ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable
The roots of a quadratic equation are the solutions that make the equation true, and they can be found by factoring the equation
Finding the roots of a quadratic equation helps to solve real-world problems and understand the behavior of quadratic functions

Definition of Factoring
Process of breaking down a quadratic into two binomials that multiply to the original expression.
01
Factoring Example: x^2 - 16
x^2 - 16 factored is (x - 4)(x + 4), showcasing difference of squares.
02
Solving Quadratics by Factoring
Set each binomial factor to zero and solve for x to find roots of the equation.
