Question

solve x^2+3x+9=0

Answer 1

Try factoring.
If factoring doesn't work, use the quadratic formula.

Answer 2

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

Answer 3

factoring is pretty easy on this one but you cant go wrong with the good ol quadratic formula

Answer 4

\[x = \frac{3}{2} (-1\pm i \sqrt{3})\] I don't think some easy factoring works here.

Answer 5

@perdomo.arturo It can't be factored.
