Solution for 1/8x^4+1/5x^3+1/4x^2+8-7/8x^4+2/5x^3-1/2x^2-8 equation: 


x in (-oo:+oo)

(1/8)*x^4-((7/8)*x^4)+(1/5)*x^3+(2/5)*x^3+(1/4)*x^2-((1/2)*x^2)-8+8 = 0

(1/8)*x^4+(-7/8)*x^4+(1/5)*x^3+(2/5)*x^3+(1/4)*x^2+(-1/2)*x^2-8+8 = 0

3/5*x^3-3/4*x^4-1/4*x^2 = 0

x^2*(3/5*x-3/4*x^2-1/4) = 0

3/5*x-3/4*x^2-1/4 = 0

DELTA = (3/5)^2-(-3/4*(-1/4)*4)

DELTA = -39/100

DELTA < 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

x = 0
