      Solving Quadratic Equations by Factorising. Quadratics are algebraic expressions that include the term, x^2, in the general form, . ax^2 + bx + c. If you are on the foundation course, any quadratic equation you’re expected to solve will always have a=1, with all terms on one side and a zero on the other. Finding the roots of higher-degree polynomials is a more complicated task. Introduction to Rational Functions . Rational functions are fractions involving polynomials. A rational function f(x) has the general form shown below, where p(x) and q(x) are polynomials of any degree (with the caveat that q(x) ≠ 0, since that would result in an #ff0000 function).
