If \(p(x)=x^2-9\), which are the zeroes of \(p(x)\)?

Answer and explanation

Correct answer: (3, -3)

The zeroes are the values of \(x\) for which \(p(x)=0\). Thus, \(x^2-9=0\), or \((x-3)(x+3)=0\), giving \(x=3\) or \(x=-3\). Therefore, (3, -3) is correct. Option B is incorrect because 0 and 9 are not the values that make the polynomial zero. Exam tip: Recognise the difference-of-squares identity \(a^2-b^2=(a-b)(a+b)\) to find such zeroes quickly.
