Q. 158 - Intermediate Algebra

Question

How is the “ac” method similar to the “undo FOIL” method? How is it different?

Step-by-Step Solution

Answer

The ac gives as Write the factors as two binomials with first terms x. while the undo FOIL is 

To factor the trinomial means to start with the product, and end with the factors.

Step 1. Given Information

The problem asks to find similarity and differences between ac method and undo FOIL .

Step 2. Similarity

The AC Method is a method of factoring trinomials in the form $a{x}^2+bx+c.$

FOIL" only works for the special case of a two-term polynomial multiplied by another two-term polynomial.

Step 2. Differences

The AC method is used to factor the polynomials and undo Foil is used to find the factors in reverse order.
