Option (b) is correct.

The difference between two given polynomial is

Step-by-step explanation:

Given : Polynomial and

We have to find the difference between given two polynomial.

Consider  Polynomial and

Difference is  

Consider

Distribute parentheses, we have,

Apply plus- minus rule,

Adding similar terms (terms having same variable with same power)

We have,

Thus, the difference between two given polynomial is

i got 10.28 but that rounds up to 10.3
