Determine any common factors of the given trinomial, if common factors exist.

Set up two sets of parentheses and write the variable as the first term in each set of parentheses.

List all of the possible sets of factors for the constant term (include both positive and negative numbers).

Determine which set of factors has a sum that equals the coefficient of the first-degree term.

Write the correct factors (including their signs) as the second terms in the two sets of parentheses.

Distribute the factors to verify that they result in the original trinomial.
