Answer:

Step-by-step explanation:
The value of the discriminant informs about the nature of the roots of a quadratic function.
The discriminant Δ = b² - 4ac
• If b² - 4ac > 0, then roots are real and distinct
• If b² - 4ac = 0, then roots are real and equal
• If b² - 4ac < 0, then the roots are not real
Hence for b² - 4ac = - 8, then roots are not real
