Presentation transcript:

Factoring a Trinomial with a Front “a” Coefficient Always Check for a GCF first. Multiply “a” and “c” terms together. Find a “Magic Pair” of numbers that multiplies to the new number and still adds to the “b” term. Split “b” term into magic pair to create 2 ( ) Take GCF of Each ( ) Finish the factoring! 2x2 – 7x - 15
