Question

x²-y²/100 factorise this​

Answer 1

Answer:

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

Step-by-step explanation:

x² – y²/100

= x² - (y/10)² [a² - b² = (a + b)(a - b)]

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

Answer 2

Answer:

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

Step-by-step explanation:

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

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

a²-b² = (a+b) (a-b)

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

Answer:

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