Step-by-step explanation:

(2x-1/2x)^2 - [ (2x)^2 - (1/2x)^2)]

(2x)^2 + (1/2x) ^2 - 2×2x (1/2x) - (2x)^2 + (1/2x)^2

-2 + 2(1/2x)^2

-2 + 2×1/4x^2

-2+ 1/2x^2

I hope answer will help you so plz mark brilliant

Answer 2

Answer:

$(2x - \frac{1}{2x})(2x - \frac{1}{2x}) - (2x - \frac{1}{2x})(2x + \frac{1}{2x})$

$(2x - \frac{1}{2x})(1 - 2x - \frac{1}{2x})$

$(2x - \frac{1}{2x})( \frac{2x - 4x^{2} - 1 }{2x})$
