2x+10-(x-1)2x=0

Solution for 2x+10-(x-1)2x=0 equation:

2x+10-(x-1)2x=0

We multiply parentheses

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

We add all the numbers together, and all the variables

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

a = -2; b = 4; c = +10;
Δ = b2-4ac
Δ = 42-4·(-2)·10
Δ = 96
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:

$\sqrt{\Delta}=\sqrt{96}=\sqrt{16*6}=\sqrt{16}*\sqrt{6}=4\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4\sqrt{6}}{2*-2}=\frac{-4-4\sqrt{6}}{-4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4\sqrt{6}}{2*-2}=\frac{-4+4\sqrt{6}}{-4}
