If \((x \pm h)\) is a factor of a polynomial, then the remainder will be zero. Conversely, if the remainder is zero, then \((x \pm h)\) is a factor. Often, factorising a polynomial requires some ...

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 ...
