2x^2=-4x+24

Solution for 2x^2=-4x+24 equation:

2x^2=-4x+24

We move all terms to the left:

2x^2-(-4x+24)=0

We get rid of parentheses

2x^2+4x-24=0

a = 2; b = 4; c = -24;
Δ = b2-4ac
Δ = 42-4·2·(-24)
Δ = 208
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:

$\sqrt{\Delta}=\sqrt{208}=\sqrt{16*13}=\sqrt{16}*\sqrt{13}=4\sqrt{13}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4\sqrt{13}}{2*2}=\frac{-4-4\sqrt{13}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4\sqrt{13}}{2*2}=\frac{-4+4\sqrt{13}}{4}
