Solution for 4x^2-11X-3/9-x^2 equation: 


x in (-oo:+oo)

4*x^2-(11*X)-x^2-(3/9) = 0

4*x^2-11*X-x^2-1/3 = 0

3*x^2 = -(-11*X-1/3) // : 3

x^2 = (1/3-(-11*X))/3

x^2 = (11*X+1/3)/3 // ^ 1/2

abs(x) = ((11*X+1/3)^(1/2))/(3^(1/2))

x = ((11*X+1/3)^(1/2))/(3^(1/2)) or x = -(((11*X+1/3)^(1/2))/(3^(1/2)))

x in { ((11*X+1/3)^(1/2))/(3^(1/2)), -(((11*X+1/3)^(1/2))/(3^(1/2))) }
