  • The final type of factoring to review when working with rational expressions is factoring trinomials.
  • Read the following carefully, and talk to your teacher if you have any questions.

Trinomial is the general term for an algebraic expression with three terms.

x2 + bx + c is the only type of trinomial you need to factor for this lesson.

Look at an example to see the pattern when factoring this type of trinomial.

Factor x2+ 5x + 6.

Use these values to write the answer in factored form: (x + 2)(x + 3).

x2 + 5x + 6 = (x + 2)(x + 3)
