A) \[\left( x-\frac{y}{10} \right)\left( x-\frac{y}{10} \right)\]
B) \[\left( x+\frac{y}{10} \right)\left( x+\frac{y}{10} \right)\]
C) \[\left( y+\frac{x}{10} \right)\left( y+\frac{x}{10} \right)\]
D) \[\left( x+\frac{y}{10} \right)\left( x-\frac{y}{10} \right)\]
Correct Answer: D
Solution :
(d) \[{{x}^{2}}-\frac{1}{{{y}^{2}}}={{x}^{2}}-{{\left( \frac{y}{10} \right)}^{2}}=\left( x+\frac{y}{10} \right)\left( x-\frac{y}{10} \right)\]
