Solution for 30x^2+x-60=0 equation: 



30x^2+x-60=0

a = 30; b = 1; c = -60;
Δ = b2-4ac
Δ = 12-4·30·(-60)
Δ = 7201
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{-(1)-\sqrt{7201}}{2*30}=\frac{-1-\sqrt{7201}}{60}
$


$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{7201}}{2*30}=\frac{-1+\sqrt{7201}}{60}
$
