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
