When you are factorising quadratics you will usually use the double brackets or difference of two squares method. 1. Factorising single brackets Example of factorising an algebraic expression: Remember: 3x+6 is known as a binomial because it is an expression with two terms 2. Factorising ...
Factorising quadratics 6x2 + x - 2 is in the form ax2 + bx + c So a = 6, b = 1, c = -2 You need to find 2 numbers which multiply to give ac (in this case -12) and add to give b (in this case +1) Now list the factors of ac 1 -12 -1 12 2 -6 -2 6 3 -4...
