Solution for -(z-8/20z^3)=-(6/16z^3)+18/16z^3 equation:


z in (-oo:+oo)

-(z-((8/20)*z^3)) = (18/16)*z^3-((6/16)*z^3) // - (18/16)*z^3-((6/16)*z^3)

(8/20)*z^3+(6/16)*z^3-((18/16)*z^3)-z = 0

(8/20)*z^3+(6/16)*z^3+(-9/8)*z^3-z = 0

-7/20*z^3-z = 0

-z*(7/20*z^2+1) = 0

7/20*z^2 = -1 // : 7/20

z^2 = -20/7

-z = 0

-1*z = 0 // : -1

z = 0

z = 0
