2 Review: Simplifying fractions
Example: Another way to look at it: Completely factor and cancel like FACTORS Cancel common FACTORS Note: when “everything” cancels, you’re not left with a zero, you’re left with 1.

Feel free to send suggestions or to comment on any errors/omissions. or Thomas M. Kenyon 6455 Habgood Road Black Creek, NY 14714 It’s usually not necessary to write the 1. Why 1? Because

3 Dividing Monomials Example: Rule: When you have the same base, subtract exponents Cancel common FACTORS, always in pairs. This presentation may be used by k-12 public education teachers.

4 Simplify the coefficients the same way you would a normal fraction.
Example Simplify the coefficients the same way you would a normal fraction. In this case, both the numerator and denominator are divisible by 6. The answer may also be written in this form: Or, simply use the fraction capability of your calculator and let the calculator do the work.

Feel free to send suggestions or to comment on any errors/omissions. or Thomas M. Kenyon 6455 Habgood Road Black Creek, NY 14714 Remember, SUBTRACT EXPONENTS (do not divide the exponents) (The variables with the exponents being subtracted need to be the same.)

5 Check on your calculator…
Examples: Check on your calculator… ^ 5 enter 1024 ^ 2 ^ 10 enter 1024 This presentation may be used by k-12 public education teachers.

6 Dividing a polynomial by a monomial
Example: Divide each term in the numerator separately by the monomial in the denominator: Be careful when the exponents are the same! They cancel out.

7 Your answer will ALWAYS have the SAME number of terms
as there were in the numerator. example: Answer will have 4 terms. This presentation may be used by k-12 public education teachers.
