Question

factorise x square - y square / 100​

Answer 1

Answer:

=> ( x + y/10 ) ( x - y/ 10)

Step-by-step explanation:

Hii....☺

Here is your solution.......☺

===============================

✴ To factorise :

x² - y²/100

=> x² - ( y/10)²

=> ( x + y/10 ) ( x - y/ 10)

♦ Note: a² - b² = (a + b) (a - b) here this identity is used.

===============================

Answer 2

$\bold{Answer}$

$\bold{x² - \frac{y²}{100}}$ $\bold{=}$ $\bold{(x-\frac{y}{10}})$ $\bold{(x+\frac{y}{10}})</p><p></p><p>$

$\bold{Given \ the \: expression}$

$\bold{x^2 - \frac{y^2}{100}}</p><p>$

$\bold{We \ have \ to \ factorize \ the \ above \ expression}$

$\bold{x^2 - \frac{y^2}{100}}$

$\bold{By \ using \ Identities}$

$\bold{a^2-b^2}$ $\bold{=}$ $\bold{(a-b)}$ $\bold{(a+b)}$

$\bold{x^2-\frac{y^2}{100}}$

$\bold{a \ = \ x \ and \ b}$ $\bold{=}$ $\frac{y}{10}</p><p>$

$\bold{x^2}- \frac{y ^{2} }{100}$

$(x - \frac{y}{10})( x + \frac{y}{10} )$
