Solution for 3x^2+22x+6=0 equation:



3x^2+22x+6=0
a = 3; b = 22; c = +6;
Δ = b2-4ac
Δ = 222-4·3·6
Δ = 412
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:
$\sqrt{\Delta}=\sqrt{412}=\sqrt{4*103}=\sqrt{4}*\sqrt{103}=2\sqrt{103}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(22)-2\sqrt{103}}{2*3}=\frac{-22-2\sqrt{103}}{6} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(22)+2\sqrt{103}}{2*3}=\frac{-22+2\sqrt{103}}{6} $
