3. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents:

4. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents:
Like bases, subtract smaller from
the larger exponent to get the
new exponent and keep the same
base.

5. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents:
Like bases, subtract smaller from
the larger exponent to get the
new exponent and keep the same
base.
If the larger exponent is in the
numerator, the result goes in the
numerator.

6. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents: x5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base.
If the larger exponent is in the
numerator, the result goes in the
numerator.

7. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents: x 5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base. =x 5− 3
If the larger exponent is in the
numerator, the result goes in the
numerator.

8. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents: x 5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base. =x 5− 3
If the larger exponent is in the
numerator, the result goes in the 2
numerator. =x

9. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents: x 5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base. =x 5− 3
If the larger exponent is in the
numerator, the result goes in the 2
numerator. =x
If the larger exponent is in the
denominator, the result goes in
the denominator.

Like bases, subtract smaller from 3 9
the larger exponent to get the
x a
new exponent and keep the same
base. =x 5− 3
If the larger exponent is in the
numerator, the result goes in the 2
numerator. =x
If the larger exponent is in the
denominator, the result goes in
the denominator.

23. Algebra Cruncher Problems
Follow this link to try a couple on your own at Cool Math.
Notice when you select the “Give me a Problem” button
to try new problems, 2 rows are generated. Look
carefully between them. That red line indicates this
problem is a fraction.
Do your work in a notebook before entering your answer.
When you select “What’s the Answer?” compare your
answer with the given answer.
Keep selecting new problems until you get 3
consecutive problems correct.

29. Still a little confused?
Here’s another tiny lesson dividing a
polynomial by a monomial.
Only view the “Steps for Dividing a
Polynomial by a Monomial.”

30. It’s Practice time...
Go to the Regents Prep website to
practice dividing a polynomial by a
monomial. Only practice questions 1
through 7!
Message or Pronto me if you have
questions.

31. Shall we Play a GAME?
Check your knowledge on Dividing Polynomials by playing
Jeopardy. Ok, technically it’s called Challenge Board but
it’s the same idea! There are 4 categories: horseshoes,
handgrenades, doesn’t count, and polynomial long division.
Polynomial long division is not covered in Algebra 1 so
either stay away from this topic or challenge yourself!
You have the option to play alone or against a friend or
family member.
You could even arrange a time with a classmate to meet
on Pronto to play. Try the App Share feature to see the
same game board!

32. Congratulations!
You’ve finished the notes and practice
for Dividing a Polynomial by a Monomial.
You are now ready to proceed to the
Mastery Assignment.
Good luck!
