Solution for x^2-25x+625/4=16+625/4 equation: 


x in (-oo:+oo)

x^2-(25*x)+625/4 = 625/4+16 // - 625/4+16

x^2-(25*x)+625/4-(625/4)-16 = 0

x^2-25*x+625/4-625/4-16 = 0

x^2-25*x-16 = 0

DELTA = (-25)^2-(-16*1*4)

DELTA = 689

DELTA > 0

x = (689^(1/2)+25)/(1*2) or x = (25-689^(1/2))/(1*2)

x = (689^(1/2)+25)/2 or x = (25-689^(1/2))/2

x in { (25-689^(1/2))/2, (689^(1/2)+25)/2 }
