Question

What are the possible values of x in x^2+3x+3=0?

Answer 1

so you are being asked to solve the quadratic equation...

and you will need the general quadratic formula

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

in your question a = 1, b = 3 and c = 3

you need to be aware that the solutions are complex numbers
