If \(c\neq0\), what will be the degree of \(cx^5+2x^2-7\)?

Answer and explanation

Correct answer: \(5\)

The degree of a polynomial is the highest exponent of the variable with a non-zero coefficient. Since \(c\neq0\), the term \(cx^5\) is non-zero. Thus, the highest power of \(x\) is \(5\), so the polynomial has degree \(5\). The value \(2\) is only the degree of the term \(2x^2\), not of the entire polynomial. Exam tip: Always check whether the coefficient of the highest-degree term is zero.
