10x=2x(4x+2)

Solution for 10x=2x(4x+2) equation:

10x=2x(4x+2)

We move all terms to the left:

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


We calculate terms in parentheses: -(2x(4x+2)), so:

2x(4x+2)

We multiply parentheses

8x^2+4x

Back to the equation:

-(8x^2+4x)


We get rid of parentheses

-8x^2+10x-4x=0

We add all the numbers together, and all the variables

-8x^2+6x=0

a = -8; b = 6; c = 0;
Δ = b2-4ac
Δ = 62-4·(-8)·0
Δ = 36
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{36}=6$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-6}{2*-8}=\frac{-12}{-16}
=3/4
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+6}{2*-8}=\frac{0}{-16}
=0
