18x2+6x=2x

Solution for 18x2+6x=2x equation:

18x^2+6x=2x

We move all terms to the left:

18x^2+6x-(2x)=0

We add all the numbers together, and all the variables

18x^2+4x=0

a = 18; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·18·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*18}=\frac{-8}{36}
=-2/9
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*18}=\frac{0}{36}
=0
