Question 975755: You have two square plots formed with 100m of fencing. Determine the equation of the curve of best fit, and use the equation to determine the value of x that minimizes the area of each square.
(Must use quadratics, no derivatives/calculus)
Only thing I've seen to do is then . , .

But then solutions for x are imaginary, what do I do now?

=======================
There are no real zeroes for x, but that's not relevant.

The minimum of the parabola is the vertex @ x = -b/2a
x = -50/-4 = 12.5 --> minimum Area
Minimum area = 312.5 sq m
