After simplifying (5x^6-5x^6+8x^2-1), what will be the degree?
Answer and explanation
Correct answer: 2
Here, 5x^6 and -5x^6 are like terms, so they cancel to 0. The expression becomes 8x^2-1. Its highest exponent is 2, so the degree of the polynomial is 2. Degree 0 applies only to a non-zero constant polynomial. Exam tip: Always simplify like terms before finding the degree.
