Ireally need some one step 2: using the roots you identified in step 1, write the factorization for each polynomial. (4 points; 2 points each)

The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)

In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0. 

x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x -  8) in our factorization. 

You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times. 

Unfortunately, there are no two numbers that multiply into 16 AND add into 18. I'm sorry, but these are the only numbers that go into each.

Number That Add to 18:
0 + 18
1 + 17
2 + 16
3 + 15
4 + 14
5 + 13
6 + 12
7 + 11
8 + 10
9 + 9

Numbers That Multiply to 16:
1 × 16
2 × 8
4 × 4
