Answer 2

Well, if \[5x^2 + 100 = 0\]Then \[5x^2 = -100\]\[\implies x^2 = -20 \implies x = \sqrt{-20} = 2\sqrt{5}i\]

Answer 3

It s an equation with imaginary roots
\[\pm2\sqrt{5}i\]

Answer 4

\[{5x^2}\] + \[100\] = 0
\[{5x^2}\] = \[-100\]
which is equal to \[{x^2}\] =\[\sqrt{20}\] = \[2\] \[\sqrt{5}\]

Answer 5

by the way Its \[2\sqrt{5i}\]
