Easy -1.8 This is a trivial recall question testing the most basic fact about roots of quadratics (αβ = q from Vieta's formulas). The answer is immediate with no calculation needed, and the given expression 'p - p - q - q' simplifies to -2q, making this even more straightforward than a standard recall question.
2 The quadratic equation \(x ^ { 2 } + p x + q = 0\) has roots \(\alpha\) and \(\beta\)
Which of the following is equal to \(\alpha \beta\) ?
