(-90g^2)/216g^2+108g/216g^2+72g/216g^2=0

We multiply all the terms by the denominator


(-90g^2)+108g+72g=0

We add all the numbers together, and all the variables

(-90g^2)+180g=0

We get rid of parentheses

-90g^2+180g=0

a = -90; b = 180; c = 0;
Δ = b2-4ac
Δ = 1802-4·(-90)·0
Δ = 32400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{32400}=180$
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(180)-180}{2*-90}=\frac{-360}{-180}
=+2
$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(180)+180}{2*-90}=\frac{0}{-180}
=0
