Please come with a pencil, ready to write the quiz.

**REVIEW**

**This quiz will cover 3 things**

**1. Distributing**

To distribute you have to multiply the outside number by all the inside numbers.

*Example:*2x ( 3a - 4b + 5c )

= 6ax - 8bx + 10cx

**2. Factoring**

To factor, you have to find a number that each part can be divided by and also take out any letter than is common to all the parts.

*Example:*10ax + 25x - 15bx

= 5x ( 2a + 5 - 3b)

**3. Solving for X**

To solve for X you need X's on one side and numbers on the other. Do the opposite to get rid of a number in the wrong spot. At the end, divide by the number in front of the x to find out what 1x is. Remember, whatever you do to one side (of the equation) you always have to do to the other side.

*Example:*3x + 4 = 13

- 4 -4

3x = 9

x = 3

Sometimes we have to cross multiply first

*Example:*x 4

__ = __

10 5

Multiply the diagonals (10 x 4 and X x 5)

5x = 40

x = 8
