Question 413791: 3x^2=7 Type an exact answer, (radical)as needed rationalize the denominator
and may be more than one answer
I've been working on this since Monday, if it were a simple equation, I could solve for x and get a decimal, but the radicals and rationalizing the denominator are really confusing me.
Thank you!!

It should be a simple equation, since it's solvable in two or so steps.
Divide both sides by 3, then take the square root:
(ignore the 0, the site won't let me parse +- without something in front...)
To rationalize the denominator, multiply both top and bottom by . Hence,
