            The solution and the answer by @josgarithmetic  " highlight%28y=2%28x%2B8%29%28x-50%29%29 "  are BOTH  WRONG.

            I came to bring the correct solution. 


y = a(x+8)(x-50)

a = y%2F%28%28x%2B8%29%28x-50%29%29

a = 48%2F%28%28-10%2B8%29%2A%28-10-50%29%29

a = 48%2F%28%28-2%29%2A%28-60%29%29

a = 48%2F120 = 4%2F10 = 2%2F5 = 0.4.


highlight%28y+=+0.4%2A%28x%2B8%29%28x-50%29%29.      ANSWER

Solved.
