+118687 X^2-49
You need to be careful ChoZerr, there is no = sign in the question so there CANNOT be an answer.
Not like you have found anyway.
x^2-49 is already in its most simple form.
BUT
since it is of the from x^2 - 7^2
it can very easily be factorised to give (x-7)(x+7)
oh and IF
x^2 - 49 did really equal 0 then there are 2 answers, x=7 or x=-7
