We have the quadratic equation
[tex]36x^2=25[/tex]Let's divide both sides by 36 to obtain;
[tex]\begin{gathered} x^2=\frac{25}{36} \\ \text{get the square root of both sides, we have;} \\ x=\pm\sqrt[\pm]{\frac{25}{36}} \\ x=\pm\frac{5}{6} \end{gathered}[/tex]So, x =
[tex]\frac{5}{6}[/tex]and x is also
[tex]-\frac{5}{6}[/tex]
