What is the value of the discriminant for the quadratic equation 0=x+2+x2? Discriminant is equal to b squared minus 4 A c

Write the equation in standard form as x² + x + 2 = 0, so a = 1, b = 1, and c = 2. The discriminant is b² − 4ac = 1² − 4(1)(2) = 1 − 8 = −7. Therefore, the correct choice is negative 7.
