Solution for 4x^2+12x+9/4x^2-9 equation: 


x in (-oo:+oo)

4*x^2+(9/4)*x^2+12*x-9 = 0

25/4*x^2+12*x-9 = 0

DELTA = 12^2-(-9*4*25/4)

DELTA = 369

DELTA > 0

x = (369^(1/2)-12)/(2*25/4) or x = (-369^(1/2)-12)/(2*25/4)

x = 2/25*(3*41^(1/2)-12) or x = 2/25*(-3*41^(1/2)-12)

x in { 2/25*(-3*41^(1/2)-12), 2/25*(3*41^(1/2)-12) }
