Simplify. Write each answer in its standard form.

The correct answer is: • A polynomial is in standard form when all its terms are arranged by decreasing order of degree.

Explanation:

• We have been given a function in the question.
• We have to simplify it and further writer it in its standard form.

Step 1 of 1:
We know that in polynomial we add/subtract like terms
So,


Now, We know that the terms are written in descending order of their degree.
So, In the standard form
The given polynomial will be .
