Solution for x^2-8x+12/4x^2-16 equation: 


x in (-oo:+oo)

x^2+(12/4)*x^2-(8*x)-16 = 0

x^2+(12/4)*x^2-8*x-16 = 0

4*x^2-8*x-16 = 0

DELTA = (-8)^2-(-16*4*4)

DELTA = 320

DELTA > 0

x = (320^(1/2)+8)/(2*4) or x = (8-320^(1/2))/(2*4)

x = (8*5^(1/2)+8)/8 or x = (8-8*5^(1/2))/8

x in { (8-8*5^(1/2))/8, (8*5^(1/2)+8)/8 }
