Solution for 2x^2-110x+625=0 equation:



2x^2-110x+625=0
a = 2; b = -110; c = +625;
Δ = b2-4ac
Δ = -1102-4·2·625
Δ = 7100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{7100}=\sqrt{100*71}=\sqrt{100}*\sqrt{71}=10\sqrt{71}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-110)-10\sqrt{71}}{2*2}=\frac{110-10\sqrt{71}}{4} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-110)+10\sqrt{71}}{2*2}=\frac{110+10\sqrt{71}}{4} $
