That's not correct. In general, you would have

$x^2=\dfrac5{a^2}\implies\sqrt{x^2}=\sqrt{\dfrac5{a^2}}\implies |x|=\dfrac{\sqrt5}{\sqrt{a^2}}\implies |x|=\dfrac{\sqrt5}{|a|}$

Assuming

, you have |a|=a

, so this turns into

$|x|=\dfrac{\sqrt5}a\implies x=\pm\dfrac{\sqrt5}a$

4 and 8/10 which can the simplified by dividing the fraction by two to get 4 and 4/5.
