Solve ^@ x^2 + 5 = 0 ^@
Answer:
^@ \pm \sqrt{ 5 } i ^@
- Given: ^@ x^2 + 5 = 0 ^@
^@ \begin{align} & \implies x^2 = - 5 \\ & \implies x = \pm \sqrt{ - 5 } \\ & \implies x = \pm \sqrt{ 5 } i & [ \text{ Since } \sqrt{ -1 } = i ] \end{align}^@ - Hence, the roots of the quadratic equation are ^@ \pm \sqrt{ 5 } i. ^@
