Presentation transcript:

Factoring using the “T” Method Trinomials in the form of x2 + bx + c Three-step check list: a Trinomial b Begins with an (invisible) one  leading coefficient is one c Already tried #1 (common monomials) Use this check list. If any answers are no, this is the wrong method. If all answers are yes, follow these steps: 1. 2. 3. 4. 5. List the factors of “c” Find the pair whose sum is “b” Double check the signs Put into this framework: (x ) (x ) Check using F.O.I.L.

Remember to always try to factor out a common monomial first! 1. 4. 7. 2. 5. 8. 3. 6. 9.
