For this quadratic equation, what is the value of *

2x² + 3x - 6

b2 - 4ac;

O 51

O 64

O 57

O-39

b² - 4ac = 57

Step-by-step explanation:

To find the value of b² - 4ac

we first need to know the values of a b and c

comparing the quadratic equation given 2x² + 3x - 6 and the standard quadratic equation ax² + bx + c

we will see that

a = 2 b = 3 and c = - 6

b² - 4ac = 3² - 4 (2) (-6)

=9 + 48

=57

b² - 4ac = 57
