# Solving polynomials

We solve polynomials algebraically in order to determine the roots - where a curve cuts the $$x$$-axis.

A root of a polynomial function, $$f(x)$$, is a value for $$x$$ for which $$f(x) = 0$$.

We can be asked to solve polynomial expressions by the following methods:

• Solve $$f(x) = 0$$
• Find the roots of $$f(x)$$
• Find where $$f(x)$$ cuts the $$x$$-axis
