ok I think its        -4.8 and 0.8 .. am I correct?

pfenn1 · Answer

I got a different answer but let me recalculate
I got $$\left( \left( -4\pm \sqrt{2} \right)\over 2 \right)=-2\pm \left( \sqrt{2}\over 2 \right)$$

Sorry, I had to go make dinner for the family.  I don't know where my mistake was but if I plug -4.8 and 0.8 into the equation, they are approximately correct, so I would go with that.
