Question

**Please Help :(
I have to Solve by Completing the Square
x^2+2x+2=0

Answer 1

a perfect square is of the form: (x+b)^2

when we expand this out we get: x^2 + 2bx + b^2

compare this to what you have been given: x^2 + 2x + 2

since the middle terms have to equal: 2b = 2
and the end terms have to equal: b^2 = 2+c

i would try to find a suitable value for c that you can add to the setup
