do cancelations


subtract 180x
add 18

quadratic formula
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=35020 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 12.5712104651075, 0.0954562015591658. Here's your graph:

x=12.5712 , 0.0954







correct
you would do same with other x value to check
