$x = \pm \frac{3}{5}$ $x=+-3/5$

Explanation:

$divide both sides by 25$ $"divide both sides by 25"$

$\Rightarrow x^{2} = \frac{9}{25}$ $rArrx^2=9/25$

$take the square root of both sides$ $color(blue)"take the square root of both sides"$

$\Rightarrow x = \pm \sqrt{\frac{9}{25}} \leftarrow note plus or minus$ $rArrx=+-sqrt(9/25)larrcolor(blue)"note plus or minus"$

$\Rightarrow x = \pm \frac{3}{5}$ $rArrx=+-3/5$
