We get rid of parentheses

816m^2+20m-126m=0

We add all the numbers together, and all the variables

816m^2-106m=0

a = 816; b = -106; c = 0;
Δ = b2-4ac
Δ = -1062-4·816·0
Δ = 11236
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{11236}=106$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-106)-106}{2*816}=\frac{0}{1632}
=0
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-106)+106}{2*816}=\frac{212}{1632}
=53/408
