To determine if the roots of the quadratic equation \(x^2 + bx + c = 0\) are numerically equal and opposite in sign under the conditions \(b = 0\) and \(c < 0\), we can follow these steps: ### Step 1: Substitute the value of \(b\) Given that \(b = 0\), we can rewrite the quadratic equation: \[ x^2 + 0 \cdot x + c = 0 \] This simplifies to: ...
