Answer
Does not make sense.
The equation can quickly be solved by applying the square root property.
$25x^2-169=0$
Add $169$ to both sides:
$25x^2-169+169=0+169$
$25x^2=169$
Divide both sides by $25$. Thus, the equation becomes:
$x^2=\frac{169}{25}$
If $u^2 = d$, then $u = \sqrt d$ or $u = -\sqrt d$. Hence,
$x=±\sqrt{\frac{169}{25}}$
$x=±\frac{13}{5}$
