You can put this solution on YOUR website! to start off, you need to get x by itself, so subtract 49 from both sides.
that will leave you with x²=-49
now you need to getx, rather than x², so square root both sides.
the square root of 49 is 7
but, since 49 is negative, you need an i (which is the equivalent of -1)
so x=7i
