Question

x2 + 4x + 8 = 0 This has to do with solving quadratic equations with complex numbers.

Answer 1

then what do you do?

Answer 2

do you have to solve it?

Answer 3

like factoring?

Answer 4

You can either complete the square, or you can use the quadratic formula which will lead you to your complex roots.

Answer 5

\[x^2 + 4x + 8 = 0 \]\[x^2+4x=-8\]
\[(x+2)^2=-8+4=-4\]
\[x+2=\pm \sqrt{-4}=\pm2i\]
\[x=-2\pm2i\]
