Solution for 3/4x^2-1/2x-3/20=0 equation: 


x in (-oo:+oo)

(3/4)*x^2-((1/2)*x)-(3/20) = 0

(3/4)*x^2+(-1/2)*x-3/20 = 0

3/4*x^2-1/2*x-3/20 = 0

DELTA = (-1/2)^2-(-3/20*3/4*4)

DELTA = 7/10

DELTA > 0

x = ((7/10)^(1/2)+1/2)/(3/4*2) or x = (1/2-(7/10)^(1/2))/(3/4*2)

x = 2/3*((7/10)^(1/2)+1/2) or x = 2/3*(1/2-(7/10)^(1/2))

x in { 2/3*(1/2-(7/10)^(1/2)), 2/3*((7/10)^(1/2)+1/2) }
