Solution for 50/y=y/2 equation: 


D( y )

y = 0

y = 0

y = 0

y in (-oo:0) U (0:+oo)

50/y = y/2 // - y/2

50/y-(y/2) = 0

50*y^-1-1/2*y^1 = 0

(50*y^0-1/2*y^2)/(y^1) = 0 // * y^2

y^1*(50*y^0-1/2*y^2) = 0

y^1

(-1/2)*y^2+50 = 0

(-1/2)*y^2+50 = 0

DELTA = 0^2-(4*50*(-1/2))

DELTA = 100

DELTA > 0

y = (100^(1/2)+0)/(2*(-1/2)) or y = (0-100^(1/2))/(2*(-1/2))

y = -10 or y = 10

y in { -10, 10} 

y in { -10, 10 }
