Learn how to solve quadratic equations like (x-1) (x+3)=0 and how to use factorization to solve other forms of equations.

In this video I want to do a bunch of examples of factoring a second degree polynomial, which is often called a quadratic. Sometimes a quadratic polynomial, or just a quadratic itself, or quadratic …

So I've noticed something about factoring a quadratic equation. I'm not sure if this applies to all quadratic equations, but when you put one in the form of ax^2+bx+c=0, factor it, and then multiply a and the …

Tie together everything you learned about quadratic factorization in order to factor various quadratic expressions of any form.

We can factor quadratics by first pulling out a common factor so the result looks like a (x+b) (x+c). Created by Sal Khan.

We can factor numbers like 24 into 2x12, or 3x8, or 4x6...But how can we factor algebraic expressions? We'll see that it's a lot like a puzzle.

Let's say we wanted to factor x squared plus 4xy minus 5y squared. And at first, this looks really daunting. All of a sudden, I've introduced a y and a y squared here. I have two variables. How would …

Factoring a polynomial involves writing it as a product of two or more polynomials. It reverses the process of polynomial multiplication. We have seen several examples of factoring already. However, …

Learn how to factor quadratic expressions as the product of two linear binomials. For example, 2x²+7x+3= (2x+1) (x+3).

Factoring quadratics makes it easier to find their solutions. This article reviews factoring techniques and gives you a chance to try some practice problems.
