$\frac{x}{2} + 4 \sqrt{x} + 6 + 3 + 1 = x$
	Answered by Rasheed.Sindhi last updated on 08/Apr/22

	$\frac{x}{2} + 4 \sqrt{x} + 10 = x$ $x + 8 \sqrt{x} + 20 = 2 x$ $8 \sqrt{x} + 20 = x$ $8 \sqrt{x} = x - 20$ $64 x = x^{2} - 40 x + 400$ $x^{2} - 104 x + 400 = 0$ $(x - 100) (x - 4) = 0$ $x = 100 ∣ x = 4$ $x = 100 i s a v a l i d r o o t .$

	$x - 8 \sqrt{x} - 20 = 0$ $(\sqrt{x} + 2) (\sqrt{x} - 10) = 0$ $\Rightarrow \sqrt{x} - 10 = 0$ $\Rightarrow x = 100$
