Question

Simplify the expression.

Answer 1

start by simplifying the numerator and denominator:

Numerator: multiply both terms by y to get ...y + x
Denominator: multiply both terms by y² to get....y² - x²

So we now have:

`(y+x)/( y^(2) - x^(2) )` factor the denominator

`(y+x)/((y+x)(y-x))` Reduce

`(1)/(y-x)`
