We get rid of parentheses

408x^2-3x-8x=0

We add all the numbers together, and all the variables

408x^2-11x=0

a = 408; b = -11; c = 0;
Δ = b2-4ac
Δ = -112-4·408·0
Δ = 121
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{121}=11$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-11)-11}{2*408}=\frac{0}{816}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+11}{2*408}=\frac{22}{816}
=11/408
