![]() For example, equations such as 2 x 2 + 3 x 1 0 2 x 2 + 3 x 1 0 and x 2 4 0 x 2 4 0 are quadratic equations. If a quadratic equation can be factored, it is written as a product of linear terms. Factoring means finding expressions that can be multiplied together to give the expression on one side of the equation. An equation containing a second-degree polynomial is called a quadratic equation. Often the easiest method of solving a quadratic equation is factoring. Therefore, when solving quadratic equations by factoring, we must always have the equation in the form "(quadratic expression) equals (zero)" before we make any attempt to solve the quadratic equation by factoring. Solving Quadratic Equations by Factoring. If the product of factors is equal to anything non-zero, then we can not make any claim about the values of the factors. We can only draw the helpful conclusion about the factors (namely, that one of those factors must have been equal to zero, so we can set the factors equal to zero) if the product itself equals zero. In particular, we can set each of the factors equal to zero, and solve the resulting equation for one solution of the original equation. This shows the whole quadratic function, not just the doubled up solution. If you were trying to factor it as an equation, then you are correct in that f(x) 6(x-10)(x-10) or f(x) 6 (x-10)2. So, if we multiply two (or more) factors and get a zero result, then we know that at least one of the factors was itself equal to zero. Since you are finding solutions, not the equation, the 6 does not have any meaning because as Sal did in the beginning, 0/6 0. Put another way, the only way for us to get zero when we multiply two (or more) factors together is for one of the factors to have been zero. The algebraic common factor is x in both terms. Learn how to solve quadratic equations using factoring method, a simple and easy way to find the solutions of binomials and trinomials. ![]() The numerical factor is 3 (coefficient of x 2) in both terms. Here are the steps to solve quadratic equations by factoring: Step 1: Rewrite The Quadratic Equation in Standard Form. Solving quadratic equations by factoring is an essential skill as it provides the basis for working with other complex mathematical concepts, such as graphing quadratic equations. Consider this quadratic equation: 3x 2 + 6x 0. Solving Quadratic Equations by Factoring. Zero-Product Property: If we multiply two (or more) things together and the result is equal to zero, then we know that at least one of those things that we multiplied must also have been equal to zero. Let us solve an example to understand the factoring quadratic equations by taking the GCD out.
