    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
