What is the zero of the linear polynomial (3x-6)?
Answer and explanation
Correct answer: 2
A zero of a polynomial is a value of x that makes the polynomial equal to 0. Setting 3x-6=0 gives 3x=6, so x=2. Substituting x=-2 gives 3(-2)-6=-12, so -2 is not a zero. Exam tip: The zero of a linear polynomial ax+b is -b/a.
