s=7,6s2

Solution for s=7,6s2 equation:

s=7.6s^2

We move all terms to the left:

s-(7.6s^2)=0

We get rid of parentheses

-7.6s^2+s=0

a = -7.6; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·(-7.6)·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*-7.6}=\frac{-2}{-15.2}
=2/15.2
$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-7.6}=\frac{0}{-15.2}
=0
