After simplifying (11x^7-11x^7+3x^3+2), what will be the degree?
Answer and explanation
Correct answer: 3
On subtracting the like terms, \(11x^7-11x^7=0\). Thus, the simplified polynomial is \(3x^3+2\). The highest power of \(x\) is 3, so its degree is 3. Option 7 is incorrect because the \(x^7\) terms cancel out. Exam tip: Always simplify a polynomial before finding its degree.
