Question

9x^2=25
x=??????

Answer 1

x^2/9 = 25/9
take the square roots
x = 5/3

Answer 2

x^2 = 25/9
x = sqrt(25/9)
x = sqrt(25)/sqrt(9)
x = 5/3

Answer 3

\[\LARGE{9x^2=25}\]\[\LARGE{x^2=\frac{25}{9}}\]\[\LARGE{x=\sqrt{\frac{25}{9}}=\frac{5}{3}}\]

Answer 4

will -5/3 also work?

Answer 5

\[9x^2 = 25\]
\[\sqrt{9x^2} = \sqrt{25}\]
\[\pm 3x = \pm 5\]
\[x = \pm \frac 53\]
does that answer your question?

Answer 6

\[\Huge{x=\frac{\pm5}{\pm3}}\]
