WebbAlgebraic expressions can be added and subtracted by collecting like terms, but expressions can also be multiplied and divided. Example 1. Simplify \(a \times a\). Multiplying a number or letter by itself is called squaring. This means \(a \times a = a^2\) (read as 'a squared'). In \(a^2\), the 2 is known as the index number or power. WebbThroughout section A, learners will need to manipulate the expressions before factorising into double brackets by collecting like terms or expanding single brackets and simplifying. Expressions to be factored include those with a coefficient of x squared greater than 1. Then in section B, pupils will factorise using the difference of two squares.
