### Factoring Ep.5: Factor Quadratics (Trinomials), a not = 1 - 10:16

KEY CONCEPTS:

Notice that your trinomial is a quadratic function, where the value of a is NOT equal to 1.

Use the sum-product rule

i.) find 2 numbers that multiply to your "a" and "c" value, that ALSO ADD up to your "b" value.

ii.) expand your middle term

iii.) factor by grouping

iv.) answer should be a set of binomials
