4x^2-100x^2+9=0

Solution for 4x^2-100x^2+9=0 equation:

4x^2-100x^2+9=0

We add all the numbers together, and all the variables

-96x^2+9=0

a = -96; b = 0; c = +9;
Δ = b2-4ac
Δ = 02-4·(-96)·9
Δ = 3456
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{3456}=\sqrt{576*6}=\sqrt{576}*\sqrt{6}=24\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{6}}{2*-96}=\frac{0-24\sqrt{6}}{-192}
=-\frac{24\sqrt{6}}{-192}
=-\frac{\sqrt{6}}{-8}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{6}}{2*-96}=\frac{0+24\sqrt{6}}{-192}
=\frac{24\sqrt{6}}{-192}
=\frac{\sqrt{6}}{-8}
