2. The roots of a polynomial are where the graph crosses the x-axis. Find each of the following polynomials' roots and find the factorization of the polynomial graphed.
Step 1: Identify the roots for each polynomial. You may assume that each graph crosses the axes at a tick mark. (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.
