If \(p(x)=ax^4+bx^3+cx^2+d\), where \(a=0\), \(b=0\), and \(c\ne 0\), what is the degree of \(p(x)\)?

Answer and explanation

Correct answer: 2

Since \(a=0\) and \(b=0\), the terms \(ax^4\) and \(bx^3\) disappear. Because \(c\ne 0\), the term \(cx^2\) definitely remains, giving \(p(x)=cx^2+d\). Therefore, the degree is \(2\). The constant term \(d\) does not change the degree. Exam tip: the degree of a polynomial is the exponent of the highest-power term with a non-zero coefficient.
