#SOLVE A QUADRATIC EQUATION BY FACTORING HOW TO#

One advantage of using factoring to solve quadratic equations is that it can sometimes be easier than other methods.

Factoring is one method that can be used, and it has some advantages and disadvantages that should be considered before deciding whether or not to use it. There are a few different methods that can be used to solve quadratic equations, and each has its own set of pros and cons. Pros and Cons of Using Factoring to Solve Quadratic Equations The only numbers that fit this criteria are 1 and 4, so our final answer is (x-1)(x-4). Now we need to find two numbers that multiply together to equal 1 (the coefficient of x^2) and add up to equal 5 (the coefficient of x^1). The first and last terms have a common factor of 1, so we group them together: (x^2+x)+(5x+6). Once we have these numbers, we can write them as factors of our original equation.įor example, let’s look at the equation x^2+5x+6. We group these terms together and then find two numbers that multiply together to equal the first term and add up to equal the second term. To factor by grouping, we need to look at the factors of the first and last terms of the equation (the coefficients of x^2 and x^0). There are a few different methods that can be used to factor an equation, but we will focus on one method in particular: factoring by grouping. In the case of quadratic equations, we are looking to break down the equation into smaller parts that can be multiplied together to equal the original equation.

How to Solve Quadratic Equations by Factoringįactoring is a process of breaking something down into smaller pieces. Factoring is a helpful way to solve quadratic equations because it can often simplify an equation so that it is easier to solve. So, in the equation x^2+5x+6=0, the factors would be (x+3)(x+2). The factors of a polynomial are the values that can multiply together to give you the original equation. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. In mathematics, this usually means finding the factors of a number. What is Factoring?įactoring is the process of breaking a number or expression down into its component parts. The most common way to solve a quadratic equation is by factoring. If a = 0, then the equation is linear, not quadratic. What is a Quadratic Equation?Ī quadratic equation is an equation that can be written in the form ax^2 + bx + c = 0, where a, b, and c are real numbers and x is an unknown. In this blog post, we will explore the box method and the difference between factoring by grouping and factoring by taking out the greatest common factor. There are a few different methods that can be used to factor a quadratic equation. For example, the equation x2 + 5x + 6 can be expressed as (x + 2)(x + 3). The process of solving a quadratic equation by factoring involves expressing the equation as the product of two binomials. A quadratic equation is an equation that contains a term with an exponent of 2, such as x2 + 5x + 6. The process of factoring is often used in solving quadratic equations. For example, the number 12 can be expressed as 2 x 2 x 3, or as 1 x 12. In other words, it’s a way of expressing a number as the product of its factors. Solving Quadratic Equations Using Factoringįactoring is a mathematic process involving the decomposition of a number or algebraic expression into its prime factors.
