What is the value of the discriminant for the quadratic equation 0=2x2+x−3? Discriminant is equal to b squared minus 4 A c
Answer
A
negative 23
B
25
C
negative 25
D
26
Explanation
For 2x² + x − 3 = 0, the coefficients are a = 2, b = 1, and c = −3. Using the discriminant formula b² − 4ac gives 1² − 4(2)(−3) = 1 + 24 = 25. The correct choice is 25.
