Part II

Rule 10: To add rational numbers:Case 1 (Signs Alike)

Determine the sum of their absolute values and keep the sign.

Case 2 (Signs Different)

Determine the difference of their absolute values and take the signof the number having the larger absolute value.


 Rule 11: Let a and b be rational numbers:a - b = a + (-b)


Rule 12: To multiply rational numbers, multiply their absolute values.If the numbers have like signs, the answer will be positive. If the numbershave unlike signs, the answer will be negative.Examples:


The sign rule for division is similar to the rule for multiplication.

Practice Problems:Answers:
a) (2x-3y)2(3xy)3a) 
b) b) 
The following examples illustrate operations with polynomials.Examples:


Practice Problems: Perform the operation. 



Rule 17: To factor polynomials:1) Factor out the greatest common factor.

2) If you have two terms, use a formula.a2 - b2 = (a - b)(a + b)

a3 - b3 = (a - b)(a2 + ab + b2)

a3 + b3 = (a + b)(a2 - ab + b2)3) If you have three terms, use trial and error.

4) If you have more than three terms, try to group to create one ofthe above conditions.

5) Be sure to repeat above steps until all factors are prime.
