15 <p>To apply the remainder theorem, substitute the root of the divisor into the polynomial. For a divisor of the form (x - a), substitute x = a into the polynomial. The result of this substitution is the remainder. For example, if P(x) is the polynomial and (x - a) is the divisor, then: Remainder = P(a)</p>
