Question

Is my answer right? :)
Solve. 2x2 + 3x = -8

-3 _+_ 11i/4

Answer 1

here's the correct answer \[\large \frac{ -3 \pm \sqrt{55}i }{ 4 }\]
here's the part where you made the mistake:\[\large \frac{ -3 \pm \sqrt{9-64} }{ 4 }=\frac{ -3 \pm \color{red}{(i \sqrt9 +i \sqrt{64})} }{ 4 }=\frac{ -3 \pm \color{red}{11i} }{ 4 }\]
