1. 2.3 – Factoring Polynomials Simple Trinomials

2. A simple trinomial is a quadratic expression where the leading coefficient is a 1. To factor a simple trinomial you need to find two integers that add up to b and multiply to give c.

3. Factor: ___ + ___ = 9 =( )( ) ___ x ___ = 14 Factors of 14 1 x 14 2 x 7

4. Factor: ___ + ___ = 8 =( )( ) ___ x ___ = 15 Factors of 15 1 x 15 3 x 5

5. Factor: ___ + ___ = 2 =( )( ) ___ x ___ = -24 Factors of 24 1 x 24 2 x 12 3 x 8 4 x 6

6. Factor: ___ + ___ = -9 ___ x ___ = 20 = ( )( ) Factors of 20 1 x 20 2 x 10 4 x 5

7. Factor: ___ + ___ = -10 ___ x ___ = +21 = ( )( ) Factors of 21 1 x 21 3 x 7

8. Factor: ___ + ___ = 6 DNF (Does Not Factor) ___ x ___ = -3 Factors of 3 1 x 3 Nothing works!
