Summary

a polynomial is the name given to a sum of algebraic terms. the terms are usually arranged in descending order of their powers.

the degree of this polynomial is the highest power of x.

polynomials can be given in factorised form.

the value of a polynomial is calculated by substituting a value for the variable(s) into the polynomial.

Key Skills
  • substitute a value into a polynomial
