4x^2+2x=32

Solution for 4x^2+2x=32 equation:

4x^2+2x=32

We move all terms to the left:

4x^2+2x-(32)=0

a = 4; b = 2; c = -32;
Δ = b2-4ac
Δ = 22-4·4·(-32)
Δ = 516
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:

$\sqrt{\Delta}=\sqrt{516}=\sqrt{4*129}=\sqrt{4}*\sqrt{129}=2\sqrt{129}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{129}}{2*4}=\frac{-2-2\sqrt{129}}{8}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{129}}{2*4}=\frac{-2+2\sqrt{129}}{8}
