- This problem is about finding zeroes with a polynomial and also find imaginary zeroes. First we begin by finding the possible rational zeroes. This helps us to know how many possible zeroes there are. Then we use the Descartes rule of signs to help us determine the positive and negative real zeroes. After that we use the synthetic division to help us find the zeroes.
- However, one thing we must remember to keep sign for even power and change odd power when doing the Descartes rule of signs for negative real zeroes.

This problem is about factoring equation in order to find the equation. In this problem you are trying to find the x-int, y-int, zeros (with multiplicities), and end behavior. This will help you find the zeros (with multiplicities) and end behavior so you can graph it.
Special attention is needed for graphing the equation. We must remember T=1, B=2, C=3, T stands for through, B stand for bounce, and C stand for curve. Which allows us to graph the function more accurate.

This problem is about identifying x-intercept, y-intercept, vertex (max/min), axis of symmetry and graphing them. In order to find the solution you should follow the steps. Which will make the answer and graph more accurate.
Special attention is needed for finding the x-intercept. You need to plug zero in the first equation and then to find the exact x-intercept. Press 2nd and find the radical then plug the number into the calculator.
