After simplifying (6x^3-6x^3+9x-2), what will be the degree?
Answer and explanation
Correct answer: 1
On simplification, the like terms cancel: \(6x^3-6x^3=0\). The polynomial left is \(9x-2\). The highest power of \(x\) in it is \(1\), so its degree is \(1\). Degree 0 would apply only to a non-zero constant polynomial, but \(9x\) is present here. Exam tip: simplify like terms first, then identify the highest exponent of the variable remaining.
