Question

factorise x ^2 -y^2/100

Answer 1

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.

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

Thanks...☺

Answer 2

Answer:

$x^2-\frac{y^2}{100}=(x-\frac{y}{10})(x+\frac{y}{10})$

Step-by-step explanation:

Given the expression

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

we have to factorize the above expression.

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

Using identity,

$a^2-b^2=(a-b)(a+b)$

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

$a=x\text{ and }b=\frac{y}{10}$

$x^2-\frac{y^2}{100}=(x-\frac{y}{10})(x+\frac{y}{10})$
