Solution for 7/2x+1-8x/2x-1=-4 equation: 


x in (-oo:+oo)

(7/2)*x-(((8*x)/2)*x)-1+1 = -4 // + 4

(7/2)*x-(((8*x)/2)*x)-1+1+4 = 0

(7/2)*x-4*x^2-1+1+4 = 0

7/2*x-4*x^2+4 = 0

DELTA = (7/2)^2-(-4*4*4)

DELTA = 305/4

DELTA > 0

x = ((305/4)^(1/2)-7/2)/(-4*2) or x = (-(305/4)^(1/2)-7/2)/(-4*2)

x = ((305/4)^(1/2)-7/2)/(-8) or x = ((305/4)^(1/2)+7/2)/8

x in { ((305/4)^(1/2)-7/2)/(-8), ((305/4)^(1/2)+7/2)/8 }
