    Answer: x = 41.22 and 38.78

    Step-by-step explanation:

    Given the equation

    4x² - 40x + 94 = 0

    Using the general formula

    x = - b+/-√b²-4ac/2a

    Where a = 4, b = - 40 c = 94

    x = - (-40) + / -√ (-40) ²-4 (4) (94) / 2 (4)

    x = 40+/-√1600-1504/8

    x = 40 + / -√96/8

    x = 40 + / -9.8/8

    x = 40+/-1.22

    x = 40+2.22 = 41.22

    and x = 40 - 1.22

    x = 38.78
