Solving Polynomial Expressions

Solving a function \(f(x)\) means finding the values of \(x\) that satisfies the equation \(f(x) = 0\). There are several ways of doing this such as polynomial factoring, factoring by substitution, factoring by grouping, etc. or quadratic equation.

Imaginary Numbers

The \(\sqrt{-1}\) is defined as \(i\) which is just an imaginary constant.

Communication

If the question doesn’t specify, include the values of not real (complex) roots. If the question specifies \(x\epsilon\mathbb{R}\) then only include real roots.
