Answer: Yes, the degree of sum is differ from the degree of difference.
Step-by-step explanation:
Degree of a polynomial is a highest power of its monomials ( single term).
Here, the given polynomials are,
By adding these two polynomials,
Since, the highest power of x in this result = 7
Hence, the degree of sum of the given polynomials = 7
Now, by subtracting the given polynomials,
Since, the highest power of x in this result = 5,
Hence, the degree of difference of the given polynomials = 5
Thus, both the degree of sum and difference are different.
