anonymous · Answer

Find two numbers when you multiply them by each other they will give you three and when you add them together they give you -2.

Thank you Bob I have tried to do that but this quadratic problem is not factor-able, and I don't know what else to do. I am currently trying to "complete the square" but this is not going too well.

How about you use the quadratic formula?

the_fizicx99 · Answer

Completing the square is a more tedious process compared to using the Quadratic formula. 

I can help you with completing the square, however I recommend using the formula.

Are you sure the equation has no typo?

mathmate · Answer

Completing the square:
$$x^2-2x+3=0$$
$$(x-1)^2-1+3=0$$
$$(x-1)^2=-2$$
Solving for x-1
$$(x-1)=\sqrt{-2}$$
$$x=1\pm\sqrt{2}i $$

I confused it I did 

x^2 - 2x -1 +1 +3 = 0

I thought eh x^2 -2x +1 are the ones that factor without the -1. 

Good Job!
