Question : If $\sqrt{5x-6}+\sqrt{5x+6}=6$, then what is the value of $x$?
Option 1: – 4
Option 2: 0
Option 3: 2
Option 4: 4
Correct Answer: 2
Solution : Given: $ \sqrt{5x-6}+\sqrt{5x+6}=6$ Squaring both sides, ⇒ $(\sqrt{5x-6}+\sqrt{5x+6})^2=6^2$ ⇒ $(5x-6)+(5x+6)+2(\sqrt{5x-6}\sqrt{5x+6})=36$ ⇒ $10x+2(\sqrt{25x^2-36} )=36$ ⇒ $(\sqrt{25x^2-36} )=18-5x$ Again, squaring both sides, ⇒ $({25x^2-36} )=324+25x^2-180x$ ⇒ $324+36 =180x$ ⇒ $360 =180x$ ⇒ $ x=\frac{360}{180}$ $\therefore x =2$ Hence, the correct answer is 2.
