anonymous · Answer

do you know the quadratic formula, meow?

anonymous · Answer

formula for this one 
use 
$$x=\frac{-3\pm\sqrt{3^2-4\times 2\times 6}}{2\times 2}$$

anonymous · Answer

once you see that the number under the radical is negative (clearly) you will say "no solution"

anonymous · Answer

don't forget, as corky said, solution to 
$$ax^2+bc+c=0$$ is 
$$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$
