After simplifying (4x^4-4x^4+7x-2), what will be the degree?
Answer and explanation
Correct answer: 1
On combining like terms, \(4x^4-4x^4=0\). Thus, the simplified polynomial is \(7x-2\). The highest power of \(x\) in it is 1, so its degree is 1. Choosing 4 is incorrect because the \(x^4\) terms cancel each other. Exam tip: Always simplify a polynomial before finding its degree.
