Let \(p(x)=ax+b\), where \(a\) and \(b\) are real numbers and \(a\ne0\). Which statement is always true about this linear polynomial?

Answer and explanation

Correct answer: It has exactly one zero.

Putting \(p(x)=0\) gives \(ax+b=0\), so \(x=-\frac{b}{a}\). Since \(a\ne0\), this is one definite real number; hence there is exactly one zero. Two distinct zeros may occur for a quadratic polynomial. Exam tip: a linear polynomial has degree 1.
