Factoring Objective: To factor trinomials of the form ax 2 + bx + c

Problem 1 Factor the following: Now, we are interested in the outer and inner products that have a sum of 11 (FOIL).

Problem 1 Factor the following: Now, we are interested in the outer and inner products that have a sum of 11 (FOIL). The start is easy. Now, where do we put the 1 and where do we put the 2?

Problem 1 Factor the following: Now, we are interested in the outer and inner products that have a sum of 11 (FOIL). The start is easy. Now, where do we put the 1 and where do we put the 2?

Problem 1 Factor the following: Now, we are interested in the outer and inner products that have a sum of 11 (FOIL). The start is easy. Now, where do we put the 1 and where do we put the 2?

Got it? Factor the following: Now, we are interested in the outer and inner products that have a sum of 13 (FOIL). I will give you this start:

Got it? Factor the following: Now, we are interested in the outer and inner products that have a sum of 13 (FOIL). I will give you this start:

Problem 2 Factor the following: Now, we are interested in the outer and inner products that have a difference of 4 (FOIL).

Problem 2 Factor the following: Now, we are interested in the outer and inner products that have a difference of 4 (FOIL). Again, the start is easy. Now we need to put the factors of 15 in the right place.

Problem 2 Factor the following: Now, we are interested in the outer and inner products that have a difference of 4 (FOIL).

Problem 2 Factor the following: Now, we are interested in the outer and inner products that have a difference of 4 (FOIL).

Problem 2 Factor the following: Now, we are interested in the outer and inner products that have a difference of 4 (FOIL). The outer is 9 and the inner is 5, a difference of 4. Since the 4 is positive, the 9 must be positive.

Got it? Factor the following: Now, we are interested in the outer and inner products that have a difference of 31 (FOIL).

Got it? Factor the following: Now, we are interested in the outer and inner products that have a difference of 31 (FOIL).

Got it? Factor the following: Now, we are interested in the outer and inner products that have a difference of 31 (FOIL).

Got it? Factor the following: Now, we are interested in the outer and inner products that have a difference of 31 (FOIL). Since the 31 is positive, the 35 must be positive.

Problem 4 The first step to any factoring is seeing if there is a GCF monomial that can be factored out first. For example:
