Title: Section 5'2 Factoring Trinomials
1Section 5.2Factoring Trinomials
2Using FOIL we find the product of two binomials.
3The two binomials represent the trinomial in
factored form.
Our job in this section is to rewrite simple
trinomials in factored form.
4Stare with the trinomial and pretend that you
have a factorization.
5Factoring a Trinomial
First list the factors of 24.
Check with Multiplication.
Now add the factors.
