2x(x-2)=4x^2-3x

Solution for 2x(x-2)=4x^2-3x equation:

2x(x-2)=4x^2-3x

We move all terms to the left:

2x(x-2)-(4x^2-3x)=0

We multiply parentheses

2x^2-4x-(4x^2-3x)=0

We get rid of parentheses

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

We add all the numbers together, and all the variables

-2x^2-1x=0

a = -2; b = -1; c = 0;
Δ = b2-4ac
Δ = -12-4·(-2)·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

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