Solution for 5x^2+60x+117=0 equation:



5x^2+60x+117=0
a = 5; b = 60; c = +117;
Δ = b2-4ac
Δ = 602-4·5·117
Δ = 1260
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:
$\sqrt{\Delta}=\sqrt{1260}=\sqrt{36*35}=\sqrt{36}*\sqrt{35}=6\sqrt{35}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(60)-6\sqrt{35}}{2*5}=\frac{-60-6\sqrt{35}}{10} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(60)+6\sqrt{35}}{2*5}=\frac{-60+6\sqrt{35}}{10} $
