2x^2-2x+4=34

Solution for 2x^2-2x+4=34 equation:

2x^2-2x+4=34

We move all terms to the left:

2x^2-2x+4-(34)=0

We add all the numbers together, and all the variables

2x^2-2x-30=0

a = 2; b = -2; c = -30;
Δ = b2-4ac
Δ = -22-4·2·(-30)
Δ = 244
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:

$\sqrt{\Delta}=\sqrt{244}=\sqrt{4*61}=\sqrt{4}*\sqrt{61}=2\sqrt{61}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-2\sqrt{61}}{2*2}=\frac{2-2\sqrt{61}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+2\sqrt{61}}{2*2}=\frac{2+2\sqrt{61}}{4}
