Yes, the quadratic formula is:
x=(-b±√(b²-4ac))/(2a)
what you need inside the square-root sign is
b²-4ac
How to figure out the temperature of a lake using x for the feet or the Depth and for the degrees Celsius, use (3900x+1000) /(3x^2+100) with the answer of the degrees Celsius being 6.74 looking like
6.74=(3900x+1000)/(3x^2+100)
i need the depth
i have figure out that
a=-20.22
b= 3900
c= 326

Reject the negative one, and retain the positive root which is a little under 200.
