I don't recommend "using square roots", but have you considered adding 36? That would be the place to start.

I get it. Thus my question. Have you considered adding 36? That would be the place to start.

Answer 8

\[ 144x^2-36=0\\
144x^2=36\\
x^2=\frac{36}{144}\\
x^2=\frac{1}{4}\\
x=\pm\sqrt{\frac{1}{4}}\\
x=\pm\frac{1}{2}\]

The method on the site is correct too, although a bit longer.
