Solution for 1/4x^2-3x=8 equation: 


x in (-oo:+oo)

(1/4)*x^2-(3*x) = 8 // - 8

(1/4)*x^2-(3*x)-8 = 0

(1/4)*x^2-3*x-8 = 0

1/4*x^2-3*x-8 = 0

DELTA = (-3)^2-(-8*1/4*4)

DELTA = 17

DELTA > 0

x = (17^(1/2)+3)/(1/4*2) or x = (3-17^(1/2))/(1/4*2)

x = 2*(17^(1/2)+3) or x = 2*(3-17^(1/2))

x in { 2*(3-17^(1/2)), 2*(17^(1/2)+3) }
