Question

Which of the following are solutions to the equation?
x^2 + 2x + 2 = 0

Answer 1

Well you can use the quad formula to determine the solutions :)

For this you need to compare it with the standard form which is

\[\huge\ ax^2+bx+c=0\]

The quad formula is,

\[\huge\ x=\frac{ -b \pm \sqrt {b^2-4ac}} { 2a }\]

Answer 2

I got B is this correct?

Answer 3

To check if your answer is correct put it in your equation and check if

LHS=RHS

If yes then you are correct :)
