3x^2-18x+29=8
We move all terms to the left:
3x^2-18x+29-(8)=0
We add all the numbers together, and all the variables
3x^2-18x+21=0
a = 3; b = -18; c = +21;
Δ = b2-4ac
Δ = -182-4·3·21
Δ = 72
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{72}=\sqrt{36*2}=\sqrt{36}*\sqrt{2}=6\sqrt{2}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-6\sqrt{2}}{2*3}=\frac{18-6\sqrt{2}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+6\sqrt{2}}{2*3}=\frac{18+6\sqrt{2}}{6} $
