Hi
completing the square
x^2+2x = 2
recommend thinking what would 'come in handy' to get (x+1)^2 on left side...
and adding that number 1 to both sides of the equation.
(x+1)^2 = 3
You can put this solution on YOUR website!
Take 1/2 of the coefficient of , square it,
and add it to both sides
The left side is now a perfect square
Now take the square root of both sides answer
and answer
------------------
These 2 answers are the roots. You can check

Multiplying this out,
OK
