Solution for r/2(3/4-4r)=(r/4-1/2)(1/2-8r) equation: 


r in (-oo:+oo)

(r/2)*(3/4-(4*r)) = (r/4-(1/2))*(1/2-(8*r)) // - (r/4-(1/2))*(1/2-(8*r))

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

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

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

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

1/4-15/4*r = 0

1/4-15/4*r = 0

1/4-15/4*r = 0 // - 1/4

-15/4*r = -1/4 // : -15/4

r = -1/4/(-15/4)

r = 1/15

r = 1/15
