Solution for 2x(3x-4)=10x equation:

2x(3x-4)=10x

We move all terms to the left:

2x(3x-4)-(10x)=0

We add all the numbers together, and all the variables

-10x+2x(3x-4)=0

We multiply parentheses

6x^2-10x-8x=0

We add all the numbers together, and all the variables

6x^2-18x=0

a = 6; b = -18; c = 0;
Δ = b2-4ac
Δ = -182-4·6·0
Δ = 324
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{324}=18$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-18}{2*6}=\frac{0}{12}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+18}{2*6}=\frac{36}{12}
=3
