    Answer:

    x= -7           x = 2

    Step-by-step explanation:

    f(x)= x^2 + 5x – 14

    To find the x intercepts, set the function equal to zero

    0 = x^2 + 5x – 14

    Factor

    What two numbers multiply to -14 and add to 5

    7*-2 = -14

    7+-2 = 5

    0= (x+7) (x-2)

    Using the zero product property

    x+7 =0      x-2 =0

    x= -7           x = 2
