Solution for (x-1/2)2-4=0 equation: 


x in (-oo:+oo)

(x-(1/2))^2-4 = 0

(x-1/2)^2-4 = 0

(x-1/2)^2-4 = 0

x^2-x-15/4 = 0

x^2-x-15/4 = 0

x^2-x-15/4 = 0

DELTA = (-1)^2-(-15/4*1*4)

DELTA = 16

DELTA > 0

x = (16^(1/2)+1)/(1*2) or x = (1-16^(1/2))/(1*2)

x = 5/2 or x = -3/2

(x+3/2)*(x-5/2) = 0

(x+3/2)*(x-5/2) = 0

( x+3/2 )

x+3/2 = 0 // - 3/2

x = -3/2
