0=2x^2+12x+16

Solution for 0=2x^2+12x+16 equation:

0=2x^2+12x+16

We move all terms to the left:

0-(2x^2+12x+16)=0

We add all the numbers together, and all the variables

-(2x^2+12x+16)=0

We get rid of parentheses

-2x^2-12x-16=0

a = -2; b = -12; c = -16;
Δ = b2-4ac
Δ = -122-4·(-2)·(-16)
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

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