Can this problem be solved?

The discriminant is -23

The equation has 0 real solution

Step-by-step explanation:

The discriminant of the quadratic equation ax² + b x + c = 0 is Δ = b² - 4ac

Let us use the rule above to solve the question

∵ x² - x + 6 = 0

∴ a = 1, b = -1 and c = 6

∵ Δ = b² - 4ac

∴ Δ = (-1)² - 4(1)(6)

∴ Δ = 1 - 24

∴ Δ = -23

∴ The discriminant is -23

∵ -23 < 0

∴ Δ < 0

∴ The equation has no real solutions

∴ The equation has 0 real solution
