\frac{x}{4}  = \frac{1}{2x }\\\\x\neq 0 \\\\2x^2=4\ \ | \ divide \ both \ sides\  by\  2          \\\\ x^2=2 \\\\x^2-2=0 \\\\(x-\sqrt{2})(x+\sqrt{2})=0\\\\ x-\sqrt{2}=0 \ \ or \ \  x+\sqrt{2}=0 \\\\x=\sqrt{2}  \ \ or \ \  x=-\sqrt{2}

cross multiplication. bale diba x/4=1/2 magiging 2x=4, tas divide sa two tas makukuha mo x=2.
hala hindi pala dito. sori
not ! quadratic equation x/4 =1/(2x)
ahh. ou nga
