Which of the following quadratic polynomials has two identical linear factors?

Answer and explanation

Correct answer: \(x^2-10x+25\)

For \(x^2-10x+25\), the discriminant is \(b^2-4ac=(-10)^2-4(1)(25)=0\), so it has equal linear factors: \((x-5)^2\). Option B has a positive discriminant and therefore two distinct factors. Exam tip: a zero discriminant indicates a repeated factor.
