Solution for x^2-x=7/4 equation: 


x in (-oo:+oo)

x^2-x = 7/4 // - 7/4

x^2-x-(7/4) = 0

x^2-x-7/4 = 0

x^2-x-7/4 = 0

DELTA = (-1)^2-(-7/4*1*4)

DELTA = 8

DELTA > 0

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

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

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