1 Factoring – Trinomials 2 The other type of trinomial has a coefficient greater than one in front of the first squared term. We will use binomial factors to get our answer.

2 Factoring – Trinomials 2 The other type of trinomial has a coefficient greater than one in front of the first squared term. We will use binomial factors to get our answer. EXAMPLE # 1 : Factor

3 Factoring – Trinomials 2 The other type of trinomial has a coefficient greater than one in front of the first squared term. We will use binomial factors to get our answer. EXAMPLE # 1 : Factor STEPS : 1. Multiply front coefficient by back number ( do not worry about signs )

4 Factoring – Trinomials 2 The other type of trinomial has a coefficient greater than one in front of the first squared term. We will use binomial factors to get our answer. EXAMPLE # 1 : Factor STEPS : 1. Multiply front coefficient by back number ( do not worry about signs ) 2. What factors of that number equal the middle term when added/subtracted ?
