Solution for 6x^2+12x-25=0 equation:



6x^2+12x-25=0
a = 6; b = 12; c = -25;
Δ = b2-4ac
Δ = 122-4·6·(-25)
Δ = 744
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:
$\sqrt{\Delta}=\sqrt{744}=\sqrt{4*186}=\sqrt{4}*\sqrt{186}=2\sqrt{186}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(12)-2\sqrt{186}}{2*6}=\frac{-12-2\sqrt{186}}{12} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+2\sqrt{186}}{2*6}=\frac{-12+2\sqrt{186}}{12} $
