✐ Answer:

[tex]n^2+n+2=0\quad :\quad n=-\frac{1}{2}+i\frac{\sqrt{7}}{2},\:n=-\frac{1}{2}-i\frac{\sqrt{7}}{2}[/tex]

✍️Steps:--

✰ [tex]n^2+n+2=0[/tex]

[tex]n_{1,\:2}=\frac{-1\pm \sqrt{1^2-4\cdot \:1\cdot \:2}}{2\cdot \:1}[/tex]

[tex]n_{1,\:2}=\frac{-1\pm \sqrt{7}i}{2\cdot \:1}[/tex]

[tex]n_1=\frac{-1+\sqrt{7}i}{2\cdot \:1},\:n_2=\frac{-1-\sqrt{7}i}{2\cdot \:1}[/tex]

[tex]\frac{-1+\sqrt{7}i}{2\cdot \:1}[/tex]

[tex]=\frac{-1+\sqrt{7}i}{2}[/tex]

[tex]=-\frac{1}{2}+\frac{\sqrt{7}}{2}[/tex]

[tex]\frac{-1-\sqrt{7}i}{2\cdot \:1}[/tex]

[tex]=\frac{-1-\sqrt{7}i}{2}[/tex]

[tex]=-\frac{1}{2}-\frac{\sqrt{7}}{2}[/tex]

[tex]n=-\frac{1}{2}+i\frac{\sqrt{7}}{2},\:n=-\frac{1}{2}-i\frac{\sqrt{7}}{2}[/tex]
