78x^2-13x-10=0

a = 78; b = -13; c = -10;
Δ = b2-4ac
Δ = -132-4·78·(-10)
Δ = 3289
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-\sqrt{3289}}{2*78}=\frac{13-\sqrt{3289}}{156}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+\sqrt{3289}}{2*78}=\frac{13+\sqrt{3289}}{156}
