Factorising quadratics mc-TY-factorisingquadratics-2009-1 An essential skill in many applications is the ability to factorise quadratic expressions. In this unit you will see that this can be thought of as reversing the process used to ‘remove’ or ‘multiply-out’ brackets from an expression. In this video, I demonstrate how to factor a trinomial using the diamond method or x-method and using ratios.(Recorded with https://screencast-o-matic.com) If you are factoring a quadratic like x^2+5x+4 you want to find two numbers that Add up to 5 Multiply together to get 4 Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: Factoring quadratics with a common factor Get 3 of 4 questions to level up!

Factoring of quadratic polynomials (second-degree polynomials) is done by “un-FOILing,” which means we start with the result of a FOIL problem and work backwards to find the two binomial factors.

So the "adding up to" part is the same (we're still finding factors that add up to the middle term's coefficient), but finding those factors will be harder, because we've got more information going into that stage of the process. A quadratic equation is an equation of the form ax2 + bx + c = 0, where a≠ 0, and a, b, and c are real numbers. Solving Quadratic Equations by Factoring We can often factor a quadratic equation into the product of two binomials. We are then left with an equation of the form (x + d) (x + e) = 0, where d and e are integers. But the expression has three terms, and the power on the middle term is half of the power on the leading term (being the understood 1 ), so this is of quadratic form; it's a quadratic in x1/2, and it's a simple case of factoring. x + 5 x1/2 + 4.
