x in (-oo:+oo)
1.8 = (x^2)/0.0673-x // - (x^2)/0.0673-x
x-((x^2)/0.0673)+1.8 = 0
x-14.85884101*x^2+1.8 = 0
x-14.85884101*x^2+1.8 = 0
DELTA = 1^2-(-14.85884101*1.8*4)
DELTA = 107.983655272
DELTA > 0
x = (107.983655272^(1/2)-1)/(-14.85884101*2) or x = (-107.983655272^(1/2)-1)/(-14.85884101*2)
x = -0.03365*(107.983655272^(1/2)-1) or x = 0.03365*(107.983655272^(1/2)+1)
x in { -0.03365*(107.983655272^(1/2)-1), 0.03365*(107.983655272^(1/2)+1) }
