Aim: How do we divide algebraic fractions

Homework: Algebraic fractions handout  

All Problems

Notice: Midterm Exam January 20

Test will include but not be limited to

the following topics

• Multiplying polynomials
• Factoring polynomial when a = 1
• Factoring polynomials when a is NOT = 1
• Solving quadratic equations (exponent of 2)
• Solving 1 degree linear equations (exponent of 1)
• Dividing polynomials
• Multiplying algebraic fractions
• Dividing algebraic fractions

THE 3 STEP PROCEDURE FOR DIVIDING IS AS FOLLOWS:

1. Keep the first fraction
2. Change the sign of the operation to multiplication
3. Flip(riciprocal) the 2nd fraction
4. Follow the 4 steps used for multiplying

THE 4 STEP PROCEDURE FOR MULTIPLYING IS AS FOLLOWS:
1. Factor the numerator of each fraction if possible.
2. Factor the denominator of each fraction if, possible.
3. Reduce like terms in the numerator and denominator by dividing the factors OR cross cancelation.where possible.
4. Multiply the remaining terms in the numerator and in the denominator.
