Question

If

and

,

what is ?

Answer

To solve we must first write out what is:

Now,we can simplify. However, notice that when subtracting these terms, we subtract all terms in the parentheses. Remember when we subtract a negative number, it is the same as adding the number. This is illustrated in the simplification below.

This simplifies to

Now we can combine like terms. Let's put those together and then simplify

Question

Simplify the expression below.

Answer

When simplifying the addition or subtraction of polynomials, we want to combine like terms. First, when we have a negative sign outside our parentheses, we know that we need to distribute that negative; think of it as an imaginary and use the distributive property).

Then, we combine our like terms. Be careful when subtracting.

Rearrange the expression.

Combine terms and simplify.

Question

What is ?

Answer

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 from in front of the variables and subtract them to get

After subtraction we add the variable to get .

The answer is .

Question

What is another representation of ?

Answer

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 .
