By factoring

 

x^2 + 2x + 1   = 0     can be factored as

 

(x + 1) (x + 1)  = 0

 

And setting either factor to 0  and solving, we have that 

 

x + 1 = 0      subtract 1 from both sides

 

x = -1

 

 

cool cool cool

So you do not have a general purpose email account?

Can't you make one on another computer?

Just use your mums one maybe. Or ask her (or someone else) to make one for you.  ;/
