If (k=2), what will be the degree of ((k-2)x^5+3x^2-1)?

Answer and explanation

Correct answer: \(2\)

Substituting \(k=2\) gives \((k-2)=0\), so the \(x^5\) term becomes zero. The polynomial left is \(3x^2-1\), whose highest exponent is \(2\). Therefore, its degree is \(2\). Although \(5\) appears in the original expression, that term has a zero coefficient and does not count. Exam tip: substitute the given value and remove zero-coefficient terms before finding the degree.
