X^2-120X-625=0

a = 1; b = -120; c = -625;
Δ = b2-4ac
Δ = -1202-4·1·(-625)
Δ = 16900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16900}=130$


$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-120)-130}{2*1}=\frac{-10}{2}
=-5
$


$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-120)+130}{2*1}=\frac{250}{2}
=125
