Answer 1

Answer:

Not gonna write each step its just expansion using distance formula

Step-by-step explanation:

$\frac{1}{AC}+\frac{1}{BC}\\\\\frac{1}{\sqrt{a^2t^4+a^2+2a^2t^2}}+\frac{1}{\sqrt{\frac{a^2}{t^4}+a^2+\frac{2a^2}{t^2}}}\\\\\frac{1}{a}\left[\frac{1}{t^2+1}+\frac{1}{\frac{1}{t^2}+1}\right]\\\\\frac{1}{a}$
