Factorising an expression means finding the factors that multiply together to give that expression. For \(\mathbf{x^2 + 5x + 6}\), the first step is to find two numbers whose sum is 5 and whose ...
When the expression has no constants, the highest common factor (HCF) of the coefficients is found. The expression has no constants. The HCF of the coefficients is the greatest factor that is common ...
