If \(p(x)=(a+3)x^2+5x-1\) is a linear polynomial, what is the value of \(a\)?

Answer and explanation

Correct answer: \(-3\)

A linear polynomial has degree 1, so the coefficient of \(x^2\) must be zero. Thus, \(a+3=0\), giving \(a=-3\). For example, if \(a=0\), the coefficient of \(x^2\) is 3, so the polynomial remains quadratic. Exam tip: To reduce the degree of a polynomial, set the coefficient of its highest-power term to zero.
