Question

Xsquare by 9 minus ysquarè by 25 factonse

Answer 1

Answer:

$\implies \frac{x^2}{9}-\frac{y^2}{25} \\\\ \implies \frac{x^2}{3^2}-\frac{y^2}{5^2 }\\\\\implies (\frac{x}{3} )^2-(\frac{y}{5} )^2 \\\\ \implies (\frac{x}{3}-\frac{y}{5})(\frac{x}{3}+\frac{y}{5})$

FORMULA USED :

a² - b² = (a - b) (a + b)
