Answer:
The answer to your question is below
Step-by-step explanation:
Just multiply by the reciprocal of the denominator and simplify.
The reciprocal is √y + 2.
[tex]\frac{\sqrt{y} + 2}{\sqrt{y} - 2} x \frac{\sqrt{y} + 2}{\sqrt{y} + 2}[/tex] = [tex]\frac{(\sqrt{y} + 2)^{2}}{y - 4}[/tex] = [tex]\frac{y - 4\sqrt{y} + 4}{y - 4}[/tex]
