Answer 1

Answer:

n + y

Step-by-step explanation:

a² - b² = (a +b)(a - b)

$\frac{n^{2}-y^{2}}{n+y}$ ÷ $\frac{n - y }{n + y } = \frac{(n + y)(n - y)}{(n + y)}*\frac{(n + y)}{(n - y)}$    

    { (n + y) in the denominator and numerator will be cancelled ;

       (n - y) in the denominator and numerator will be cancelled

                    = n + y
