Notice Midterm  Test  Tues January 15

• Topics to include:


• - simplifying /reduce algebraic fractions
• - mulitplying algebraic fractions 
• - Dividing algebraic fractions
• - combining algebraic fractions
• - solving equations
• scientific notation 
• solving literal equations
• combining polnomials

Homework:
Complete handout side # 1 and 2 all problems.


Lesson Review:
Remember that a rational expression is a fraction. The objective in this lesson is to combine t two algebraic fractions and reduce the answer to the most simplifed form.These expressions can be monimials or polynomials in factored or unfactored form.

THE 4 STEP PROCEDURE IS AS FOLLOWS:
1. Check for common denominator
2. Combine the numerators over the common denominator of only one fraction
3. Cancel terms or factor if possible
4. Reduce and cancel like terms.

Lesson Review:Remember that a rational expression is a fraction. The objective in this lesson is to divide two algebraic fractions and reduce the answer to the most simplifed form.These expressions can be monimials or polynomials in factored or unfactored form.

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.

Lesson Review: Remember that a rational expression is a fraction. The objective in this lesson is to simplify by reducing, fractions that have factorable expressions in the numerator and denominator. These expressions can be monimials or polynomials.

THE 3 STEP PROCEDURE FOR SIMPLIFYING IS AS FOLLOWS:

1. Factor the numerator if possible.

2. Factor the denominator, if possible

3. Reduce like terms in the numerator and denominator by dividing the factors where possible.

Homework: Complete handout  Lesson Review:

A fraction is undefined when the denominator is ZERO.

If the fraction is an algebraic fraction we need to determine

the value of the variable that makes only the denominator ZERO.

The steps for doing are:

1. Set the denominator equal to ZERO

2. Solve for the variable. NOTE that if the

denominator is a quadratic equation, there will

be two values that make the equation undefined.
