We know that any number multiplied by 0 gets 0. We have two factors when multiplied together gets 0. We find that the two terms have x in common. We can factorize quadratic equations by looking for values that are common. If the coefficient of x 2 is greater than 1 then you may want to consider using the Quadratic formula. Start by splitting the cubic polynomial into two groups (two separate binomials). Step One: Split the cubic polynomial into groups of two binomials. This is still manageable if the coefficient of x 2 is 1. In this case, we have to factor the cubic polynomial 3y³ + 18y² + y + 6 using the same grouping method as the previous example. If your quadratic equation it is in the form x 2 + bx + c 0 (in other words, if the coefficient of the x 2 term 1), it's possible (but not guaranteed) that a relatively simple shortcut can be used to factor the equation.

In other cases, you will have to try out different possibilities to get the right factors for quadratic equations. In quadratic equations where a 1, factor to (x+d )(x+e), where d × e c and d + e b. Or if you were to essentially factor out the 1/2, you could go either way on this expression. The Algebra 1 course, often taught in the 9th grade, covers Linear equations, inequalities, functions, and graphs Systems of equations and inequalities Extension of the concept of a function Exponential models and Quadratic equations, functions, and graphs. If a quadratic equation can be factored, it is written as a product of linear terms. All I did- you can see that this is just dividing both of these by 2. Listen to Sal break down the process using the quadratic formula and standard form. In some cases, recognizing some common patterns in the equation will help you to factorize the quadratic equation.įor example, the quadratic equation could be a Perfect Square Trinomial (Square of a Sum or Square of a Difference) or Difference of Two Squares. Solving quadratic equations can lead to complex solutions.

Sometimes, the first step is to factor out the greatest common factor before applying other factoring techniques. If I have an equation with one side containing factors of a given polynomial and is. The simplest way to factoring quadratic equations would be to find common factors. Main Idea of using Factoring Method to Solve a Quadratic Equation.
