Nice solution. :))

The smallest f(x) * g(x) can be is -15. (-5*3 or 5*-3)
The largest f(x) * g(x) can be is 15. (5*3 or -5*-3)
I can't see the image.
Try using the quadratic equation.
100x^2 + 20x + 1 = 25
100x^2 + 20x - 24 = 0
25x^2 + 5x - 6 = 0
(5x + 3)(5x - 2) = 0
5x + 3 = 0 or 5x - 2 = 0
I think there are no permutations because the boxes and balls are identical.
Yep.
Not sure why it was posted again.
x^2 + 2x + 5 = (x+1)^2 + 3.
At x = c, the parabola becomes a reflection of itself.
Where is c?
You're welcome. :))
The total number of ways to get to (5, 7) is 12!/5!/7!.
The total number of ways to get to (5, 7) while passing through (4, 3) is 7!/3!/3! * 5!/1/!/4!
Any idea how to solve this?
