Solving Quadratic Equations by Factoring Learning how to solve equations is one of our main goals in algebra. Up to this point, we have solved linear equations, which are of degree 1. In this section, we will learn a technique that can be used to solve certain equations of degree 2. A quadratic equation is any equation that can be written in the standard form ax2 + bx + c = 0

Factor the expression by grouping. First, the expression needs to be rewritten as 2x^ {2}+ax+bx-6. To find a and b, set up a system to be solved.
For instance, 6 is a factor of 12, 6, and 18, and x is a factor of each term. Hence 12x 3 + 6x 2 + 18x = 6x (2x 2 + x + 3). Multiplying, we get the original and can see that the terms within the parentheses have no other common factor, so we know the solution is correct.
Why solve by factoring? The most fundamental tools for solving equations are addition, subtraction, multiplication, and division. These methods work well for equations like x + 2 = 10 – 2x and 2 (x – 4) = 0. But what about equations where the variable carries an exponent, like x 2 + 3x = 8x – 6? This is where factoring comes in.

When solving linear equations, such as 2x − 5 = 21, we can solve by isolating the variable on one side and a number on the other side. However, in this chapter, we have an x2 term, so if it looks different, then it is different. Hence, we need a new method for solving trinomial equations. One method is using the zero product rule.

To solve the quadratic equation 2x2 +x − 6 = 0 by factoring, we find that the roots are x = −2 and x = 23. This is done by rewriting the equation, factoring by grouping, and then solving for x. The steps involve calculating the product of coefficients and finding the appropriate factors that add up to the specified sum.
To solve the equation, factor the left hand side by grouping. First, left hand side needs to be rewritten as 2x^ {2}+ax+bx-6. To find a and b, set up a system to be solved.
Tiger shows you, step by step, how to solve YOUR Quadratic Equations 2x^2-x-6=0 by Completing the Square, Quadratic formula or, whenever possible, by Factoring
To solve the equation x2 − 3x + 6 = 2x + 6 by factoring, follow these steps: Move all terms to one side: Start by subtracting 2x + 6 from both sides of the equation to set it equal to zero: x2 − 3x + 6 −2x −6 = 0 Simplify the equation: Combine like terms: x2 −5x = 0 Factor the equation: Look for the common factor in the terms: x(x − ...
