2.3 – Factoring Polynomials Simple Trinomials
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.
Factor: ___ + ___ = 9 ___ x ___ = 14 =( )( ) 1 x 14 2 x 7 Factors of 14
Factor: ___ + ___ = 8 ___ x ___ = 15 =( )( ) 1 x 15 3 x 5 Factors of 15
Factor: ___ + ___ = 2 ___ x ___ = -24 =( )( ) 1 x 24 2 x 12 Factors of 24 3 x 8 4 x 6
Factor: ___ + ___ = -9 ___ x ___ = 20 = ( )( ) 1 x 20 2 x 10 Factors of 20 4 x 5
Factor: ___ + ___ = -10 ___ x ___ = +21 = ( )( ) 1 x 21 3 x 7 Factors of 21
Factor: ___ + ___ = 6 ___ x ___ = -3 DNF (Does Not Factor) 1 x 3 Factors of 3 Nothing works!
