6.Write the roots of the quadratic equation: x²+8=0

Dear Student,

Please find below the solution to the asked query :

$$\begin{gathered} {\mathrm{x}}^2 + 8 = 0 \\ \Rightarrow {\mathrm{x}}^2 = -8 \\ \Rightarrow {\mathrm{x}}^2 = 8{\mathrm{i}}^2 \\ \Rightarrow \mathrm{x} = \pm 2\sqrt{2}\mathrm{i} \end{gathered}$$

Hope this would clear your doubt.

Do let us know in case of any further concerns.
