### Example Question #2 : Factoring Polynomials

Factor the polynomial **completely** and solve for *.*

**Possible Answers:**

**Correct answer:**

To factor and solve for in the equation

Factor out of the equation

Use the "difference of squares" technique to factor the parenthetical term, which provides the completely factored equation:

Any value that causes any one of the three terms , , and to be will be a solution to the equation, therefore

### Example Question #3 : Factoring Polynomials

Factor the following expression:

**Possible Answers:**

**Correct answer:**

You can see that each term in the equation has an "x", therefore by factoring "x" from each term you can get that the equation equals .

### Example Question #1 : Factoring Polynomials

Find the zeros.

**Possible Answers:**

**Correct answer:**

This is a difference of perfect cubes so it factors to . Only the first expression will yield an answer when set equal to 0, which is 1. The second expression will never cross the -axis. Therefore, your answer is only 1.
