the general form of a quadratic is ax^2 + bx + c = y and there are an infinite number of quadratic equations wihch will fit the above 2 points
what we can do is find one equation which has a = 1
Plugging in the given points
(-24)^2 - 24b + c = 7 and
(30^2 + 30b + c = 25
solving thes for ab and c gives b = (-17/3) and c = -705
so our equation would be
y = x^2 - (17/3)x - 705
