We add all the numbers together, and all the variables

-1P^2+1.24=0

a = -1; b = 0; c = +1.24;
Δ = b2-4ac
Δ = 02-4·(-1)·1.24
Δ = 4.96
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$P_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$P_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$P_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{4.96}}{2*-1}=\frac{0-\sqrt{4.96}}{-2}
=-\frac{\sqrt{}}{-2}
$
$P_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{4.96}}{2*-1}=\frac{0+\sqrt{4.96}}{-2}
=\frac{\sqrt{}}{-2}
