We can factorise lots of different types of expressions into single brackets including some quadratics like x 2 + 5 or 3x 2 – 5x. In the next example we add another layer to the idea that we can use the principle of zero products to solve equations. : Consider the terms ax^2 and cy^2 (i. Applications of Factor Theorem (AQA GCSE Further Maths)Revision Note. Factoring (factorising or factorizing) is the process of splitting an algebraic expression and writing it as a product of its factors. Multiply both to get the overall highest common factor. We will solve an equation that contains the product of a variable and a binomial.
