Solution for 1/4y2+14y-2y-4 equation: 


y in (-oo:+oo)

(1/4)*y^2+14*y-(2*y)-4 = 0

(1/4)*y^2+14*y-2*y-4 = 0

1/4*y^2+12*y-4 = 0

DELTA = 12^2-(-4*1/4*4)

DELTA = 148

DELTA > 0

y = (148^(1/2)-12)/(1/4*2) or y = (-148^(1/2)-12)/(1/4*2)

y = 2*(2*37^(1/2)-12) or y = 2*(-2*37^(1/2)-12)

y in { 2*(-2*37^(1/2)-12), 2*(2*37^(1/2)-12) }
