9-4x=3x^2-6x+2

Solution for 9-4x=3x^2-6x+2 equation:

9-4x=3x^2-6x+2

We move all terms to the left:

9-4x-(3x^2-6x+2)=0

We get rid of parentheses

-3x^2-4x+6x-2+9=0

We add all the numbers together, and all the variables

-3x^2+2x+7=0

a = -3; b = 2; c = +7;
Δ = b2-4ac
Δ = 22-4·(-3)·7
Δ = 88
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:

$\sqrt{\Delta}=\sqrt{88}=\sqrt{4*22}=\sqrt{4}*\sqrt{22}=2\sqrt{22}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{22}}{2*-3}=\frac{-2-2\sqrt{22}}{-6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{22}}{2*-3}=\frac{-2+2\sqrt{22}}{-6}
