For a quadratic expression \(ax^2+bx+c\) to have two distinct real zeroes, which statement about its discriminant is correct?

Answer and explanation

Correct answer: \(b^2-4ac>0\)

The zeroes are \(\frac{-b\pm\sqrt{b^2-4ac}}{2a}\). Two distinct real zeroes require a positive quantity inside the square root, so \(b^2-4ac>0\). If it equals zero, the two zeroes coincide. Exam tip: check the discriminant first to identify the nature of zeroes.
