It should be 12.57 i remember having that question a few months back and i got it right
The zeros are the points on the x-axis where the graph intersects.
For factorization, you do (x - the zero) for each zero, and multiply them together.
7. A. The zeros are -2 and 4.
The factorization is (x + 2)(x - 4)
7 B. The zeros are 1 and 3.
The factorization is (x - 1)(x - 3)
A great way to organize this would be to make a t-chart!
