Answer:
Explanation:
The discriminant value (denoted by Δ) of a quadratic equation in the form of ax² + bx + c = 0 is given by the expression b² - 4ac.
For the quadratic equation m² + 18m + 17 = 0, a = 1, b = 18, and c = 17. Substituting these values into the expression for the discriminant, we get:
Δ = b² - 4ac
Δ = (18)² - 4(1)(17)
Δ = 324 - 68
Δ = 256
Therefore, the discriminant value of the quadratic equation m² + 18m + 17 = 0 is 256.
