We add all the numbers together, and all the variables

8x-150*12x^2=0

Wy multiply elements

-1800x^2+8x=0

a = -1800; b = 8; c = 0;
Δ = b2-4ac
Δ = 82-4·(-1800)·0
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(8)-8}{2*-1800}=\frac{-16}{-3600}
=1/225
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(8)+8}{2*-1800}=\frac{0}{-3600}
=0
