Answer:

x=2,\\x=-2,\\x=\sqrt{3},\\x=-\sqrt{3}

Step-by-step explanation:

This is a quadratic in disguise. Let n=x^2. We can rewrite the problem as a quadratic to solve:

n^2-7n+12=0,\\(n-3)(n-4)=0,\\n=3,\: n=4.

Now plug in these values of n to solve:

\begin{cases}x^2=4, \:x=\pm 2\\\\x^2=3, x=\pm\sqrt{3}\end{cases}.

Therefore, our solutions are x=\pm 2, \:x=\pm\sqrt{3}.
