What is the discriminant of -2x² − x − 1 = 0

• 76

• -7

• 9

• none of these

• The discriminant is positive, indicating two distinct real roots.

• The discriminant is zero, indicating exactly one real root.

• The discriminant is negative, indicating two complex roots.

• The discriminant is zero, indicating two identical real roots.

• Discriminant is 0; the equation has two identical real roots.

• Discriminant is 16; the equation has two distinct real roots.

• Discriminant is -16; the equation has two complex roots.

• Discriminant is 0; the equation has no real roots.

If the discriminant is negative, then the solution will be

• one real solution
