Example Question #11 : How To Add And Subtract Polynomials In Pre Algebra
What is 
When adding polynomials you add the integers in front of like termed variables raised to the same power.
So in this case we take the numbers from, 
After addition we provide the variable 
We have the answer, 
Example Question #11 : How To Add And Subtract Polynomials In Pre Algebra
What is another representation of 
When adding polynomials, add the integers attached to the same integers raised to the same power.
So in this case we take the numbers and add 
After addition we plug the variable back in to get 
Therefore the answer is 
Example Question #12 : How To Add And Subtract Polynomials In Pre Algebra
What is 
When simplifying polynomials, only combine like terms raised to the same power.
In this case we can subtract the constants:
The answer is then 
Example Question #13 : How To Add And Subtract Polynomials In Pre Algebra
What is 
When adding polynomials you add the integers in front of like-termed variables raised to the same power.
So in this case we take the numbers and add
After addition we add the variable 
We have the answer 
Example Question #15 : How To Add And Subtract Polynomials In Pre Algebra
What is 
When subtracting polynomials you only subtract the integers in front of like-termed variables raised to the same power.
So in this case we take the numbers and subtract them
After subtraction we add the variable 
The answer is 
Example Question #13 : How To Add And Subtract Polynomials In Pre Algebra
Simplify
When adding variables raised to the same power, add the values in front of the like-termed variables. In this case, we add 
Example Question #14 : How To Add And Subtract Polynomials In Pre Algebra
Simplify
When dividing variables raised to the same power, subtract the power of the bottom term from the power of the top term. In this case, subtract
