Δ = b 2 − 4 a c Δ = 1 2 − 4 ⋅ 5 ⋅ ( − 2 ) = 1 + 40 = 41
The value of the discriminant for the quadratic equation 5 b 2 + b − 2 = 0 is 41. This indicates that there are two distinct real roots. We find this by using the formula Δ = b 2 − 4 a c and substituting the appropriate values for a, b, and c.
