We get rid of parentheses

-48s^2+8s-6s-270s=0

We add all the numbers together, and all the variables

-48s^2-268s=0

a = -48; b = -268; c = 0;
Δ = b2-4ac
Δ = -2682-4·(-48)·0
Δ = 71824
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{71824}=268$
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-268)-268}{2*-48}=\frac{0}{-96}
=0
$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-268)+268}{2*-48}=\frac{536}{-96}
=-5+7/12
