Solving and Factoring Quadratic Equations: A Comprehensive Guide

Understanding how to solve and factor quadratic equations is a fundamental skill in algebra. This article will explore how to properly factor the quadratic equation 2x^2 - 8x - 6 and provide a method to solve the equation 2x^2 - 8x - 6 0. We'll discuss various factorization methods and show step-by-step solutions.

Factorization Methods in Quadratic Equations

Quadratic equations are expressions of the form ax^2 bx c 0. To solve such equations, one common method is factoring. For the given equation 2x^2 - 8x - 6, we need to find factors that satisfy the equation's structure.

Factorizing by Grouping and Pulling Out the Greatest Common Factor (GCF)

Let's start by factoring out the greatest common factor from the equation. Notice that all the terms have a common factor of 2:

2x^2 - 8x - 6 2(x^2 - 4x - 3)

Next, we focus on factoring the quadratic expression x^2 - 4x - 3. To do this, we need to find two numbers that multiply to give -3 and add up to -4. The factors of -3 that add up to -4 are -1 and -3. Therefore, we can write:

x^2 - 4x - 3 (x - 1)(x - 3)

Thus, the original equation can be factored as:

2x^2 - 8x - 6 2(x - 1)(x - 3)

Solving the Equation 2x^2 - 8x - 6 0

To find the solutions of the equation 2x^2 - 8x - 6 0, we set the factored form equal to zero:

2(x - 1)(x - 3) 0

Since the product of the factors is zero, at least one of the factors must be zero. Therefore:

(x - 1) 0 or (x - 3) 0

Solving each equation separately:

x - 1 0 implies x 1

x - 3 0 implies x 3

Thus, the solutions to the equation 2x^2 - 8x - 6 0 are x 1 and x 3.
