Solution

The correct option is A $x^{2} + 0 x - 100 = 0$
Given,

$\Rightarrow \frac{x^{2}}{25} - 4 = 0$

$\Rightarrow \frac{x^{2} - 100}{25} = 0$

$\Rightarrow x^{2} - 100 = 0$

The standard form of the mentioned quadratic equation is
$x^{2} + 0 x - 100 = 0$ as anything multiplied by 0 gives 0,so the following equation can be written as standard form of quadratic equation.

$a n s w e r : -$
$x^{2} + 0 x - 100 = 0$
