Hey there!

 x^2 - \frac{y^2}{100}\\\text{we can write it as:}\\= (x)^2 - (\frac{y}{10})^2\\\\\text{Now using } a^2 - b^2 = (a+b)(a-b) \\=(x+\frac{y}{10})(x-\frac{y}{10})

Answer :

Step-by-step explanation :

 \sf x {}^{2}  -  \frac{y}{100}  \\  \\  \sf (x) {}^{2}  - ( \frac{y}{10} ) {}^{2}  \\  \\  \sf  \underline{using \: identity : } \\  \\  \bf a {}^{2}  - b {}^{2}  = (a + b)(a - b) \\  \\ \sf  (x) {}^{2}  - ( \frac{y}{10} ) {}^{2}  \\  \\ \sf (x +  \frac{y}{10} )(x -  \frac{y}{10} )
