108u^2+144u^2+12u+(-168u)=0

We get rid of parentheses

108u^2+144u^2+12u-168u=0

We add all the numbers together, and all the variables

252u^2-156u=0

a = 252; b = -156; c = 0;
Δ = b2-4ac
Δ = -1562-4·252·0
Δ = 24336
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{24336}=156$
$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-156)-156}{2*252}=\frac{0}{504}
=0
$
$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-156)+156}{2*252}=\frac{312}{504}
=13/21
