Solution for 3x^2-22x+18=0 equation:



3x^2-22x+18=0
a = 3; b = -22; c = +18;
Δ = b2-4ac
Δ = -222-4·3·18
Δ = 268
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:
$\sqrt{\Delta}=\sqrt{268}=\sqrt{4*67}=\sqrt{4}*\sqrt{67}=2\sqrt{67}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-22)-2\sqrt{67}}{2*3}=\frac{22-2\sqrt{67}}{6} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-22)+2\sqrt{67}}{2*3}=\frac{22+2\sqrt{67}}{6} $
