56x^2-2=22x

Solution for 56x^2-2=22x equation:

56x^2-2=22x

We move all terms to the left:

56x^2-2-(22x)=0

a = 56; b = -22; c = -2;
Δ = b2-4ac
Δ = -222-4·56·(-2)
Δ = 932
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:

$\sqrt{\Delta}=\sqrt{932}=\sqrt{4*233}=\sqrt{4}*\sqrt{233}=2\sqrt{233}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-22)-2\sqrt{233}}{2*56}=\frac{22-2\sqrt{233}}{112}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-22)+2\sqrt{233}}{2*56}=\frac{22+2\sqrt{233}}{112}
