Combine like terms and write the given polynomial in the standard form.

The correct answer is: • Two or more terms in a polynomial are like terms if they have the same variable and exponent.

• We have been given a polynomial in the question.
• We have to combine the like terms and write the polynomial in the standard form.

Step 1 of 1:
We have given polynomial .
On simplification we get

 

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