$$\begin{align} 9x^2-4&=\left(\sqrt{9x^2}+\sqrt4\right)\left(\sqrt{9x^2}-\sqrt4\right)\\&=\boxed{(3x+2)(3x-2)} \end$

Since this is a difference in squares it would simplify to (3x-2)(3x+2).

By selling a Rikshaw for rupees 2640 Ram loses 12% at what price should be sell it to gain 12%

Galina-37 [17]

Answer: Rikshaw bought it for 100. He lost 12% on selling it, so that means he must have sold it for 88. He wants to make 12% profit, so that means he should have sold it at 112.

But we know that he sold it for 2640.

Therefore, if 88 = 2640, 112 would be 2640*112/88 = 3360.
