 uadratic 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=28 is greater than zero. That means that there are two solutions: .Quadratic expression  can be factored:Again, the answer is: 2.8228756555323, 0.177124344467705. Here's your graph:

Given is x^2 - 4 = 0
-> x^2 - 2^2 = 0 ( 4 = 2^2 )

-> (x-2).(x+2) = 0 ( x^2 - a^2 = (x-a).(x+a) )
-> x-2 = 0 or x+2 = 0
-> x = 2 or x = -2
