Quick question, say I'm simplying a solution I got using the quadratic equation and I run into this:
Original version (as posted by OP):
x = -7 +- 3 sqrt(5) over 3
Edited version: $ x = \frac{-7\pm 3 \sqrt{5} }{3} $ Would the two $3$s cross each out leaving the answer to be $x = -7 \pm \sqrt{5}$, or is that illegal in terms of rules and you have to simplify all the terms, including the $-7$ if you were to simplify correctly.
Thanks!
