Expanding brackets involves using the skills of simplifying algebra ... use index laws when multiplying expressions that contain powers. For example: \(a^2 \times a^3 = (a \times a) \times ...
For example, in the expression \(3(m ... m + 3 \times 7 = 3m + 21\). Expanding brackets involves using the skills of simplifying algebra. Remember that \(2 \times a = 2a\) and \(a \times a ...
