Solution for 7/8x-5/2x^2=3/4x equation: 


x in (-oo:+oo)

(7/8)*x-((5/2)*x^2) = (3/4)*x // - (3/4)*x

(7/8)*x-((5/2)*x^2)-((3/4)*x) = 0

(-5/2)*x^2+(7/8)*x+(-3/4)*x = 0

1/8*x-5/2*x^2 = 0

DELTA = (1/8)^2-(-5/2*0*4)

DELTA = 1/64

DELTA > 0

x = ((1/64)^(1/2)-1/8)/(-5/2*2) or x = (-(1/64)^(1/2)-1/8)/(-5/2*2)

x = 0 or x = 1/20

x in { 0, 1/20 }
