Question 1174745

This is factoring and solving polynomial equations
In this case it would be a trinomial
Simplify all square roots and answers should not be decimals 
Factor or solve the following:
X⁴-16x²+48


This question might require using the slide rule which I'm not 100% sure if it will but consider using it. Thank you in advance to whoever attempts this prob!
<pre>This needs to be FACTORED since there's no EQUALS sign, as: {{{highlight_green(matrix(3,1, x^4 - 16x^2 + 48, (x^2 - 12)(x^2 - 4), (x^2 - 12)(x - 2)(x + 2))))}}}
I have absolutely no IDEA why the other person solved this when it's extremely clear that it's NOT an equation!
