What is the degree of ((x^8+x^5+1)-(x^8+x^5))?

Answer and explanation

Correct answer: 0

On subtraction, the like terms cancel:
\((x^8+x^5+1)-(x^8+x^5)=1\). The resulting polynomial, 1, is a non-zero constant polynomial, so its degree is 0. Although 8 and 5 occur in the original expression, those terms do not remain after simplification. Exam tip: Always simplify a polynomial before finding its degree; the zero polynomial has undefined degree, but the degree of 1 is 0.
