Solution for 6x^2+12x-46=0 equation:



6x^2+12x-46=0
a = 6; b = 12; c = -46;
Δ = b2-4ac
Δ = 122-4·6·(-46)
Δ = 1248
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:
$\sqrt{\Delta}=\sqrt{1248}=\sqrt{16*78}=\sqrt{16}*\sqrt{78}=4\sqrt{78}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(12)-4\sqrt{78}}{2*6}=\frac{-12-4\sqrt{78}}{12} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+4\sqrt{78}}{2*6}=\frac{-12+4\sqrt{78}}{12} $
