Answer
The equation has no real solution.
Work Step by Step
The given expression is
$\Rightarrow 5x^2+20=0$
Subtract $20$ from each side.
$\Rightarrow 5x^2+20-20=0-20$
Simplify.
$\Rightarrow 5x^2=-20$
Divide each side by $5$.
$\Rightarrow \frac{5x^2}{5}=-\frac{20}{5}$
Simplify.
$\Rightarrow x^2=-4$
$-4\leq0$ is a negative number.
Hence, the equation has no real solution.
