Solve polynomial equations using various methods and tookls which may include fctoring and synthetic division.

Example Problems for Standard 1.1a
Below are two example problems. They range from easy to difficult. f(x) = x^3 - 3x^2 - 4x + 12 Which is these is the root of f(x)? The answer is B.
 * Problem 1-Easy**
 * A.** -3
 * B.** 3
 * C.** 4
 * D.** 12

The question is telling you to put it in the graphing calculator. It will cross somewhere on the x axis, in this case it crosses at 3.


 * Problem 1 - Difficult**
 * Which equation has -1 and 3 as a solution?**

A. x^2 - 2x - 3 = 0 B. x^2 - 2x + 3 = 0 C. x^2 + 2x - 3 = 0 D. x^2 + 2x + 3 = 0 The answer is A.

This question is only difficult because it gives you where it crosses at the x axis, so you have to find the equations. The easy way of working the difficult is to grab a graphing calculator and plug in the equation. You should see where it crosses at the x axis.
