-0.5x^2+175x-3300=0
===
I graphed it and found a root at x = 20
-0.5(x^2-175x+3300) = 0
-0.5(x-20)(x-330)= 0
---
x = 20 or x = 330

Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=96100 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 330, 20. Here's your graph:
