Solution for 4x^2-16/2x-4 equation: 


x in (-oo:+oo)

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

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

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

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

DELTA = 128

DELTA > 0

x = (128^(1/2)+8)/(2*4) or x = (8-128^(1/2))/(2*4)

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

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