Solution for (7-x^1/2)/49x-x^2 equation: 


x in (-oo:+oo)

x*((7-((x^1)/2))/49)-x^2 = 0

x*((7-(x/2))/49)-x^2 = 0

(x*(7-1/2*x))/49-x^2 = 0

(x*(7-1/2*x))/49+(49*(-x^2))/49 = 0

x*(7-1/2*x)+49*(-x^2) = 0

7*x-99/2*x^2 = 0

7*x-99/2*x^2 = 0

x*(7-99/2*x) = 0

7-99/2*x = 0 // - 7

-99/2*x = -7 // : -99/2

x = -7/(-99/2)

x = 14/99

x*(x-14/99) = 0

(x*(x-14/99))/49 = 0

(x*(x-14/99))/49 = 0 // * 49

x*(x-14/99) = 0

( x-14/99 )

x-14/99 = 0 // + 14/99

x = 14/99

( x )

x = 0

x in { 14/99, 0 }
