8(8+w)(8-w)=0

Solution for 8(8+w)(8-w)=0 equation:

8(8+w)(8-w)=0

We add all the numbers together, and all the variables

8(w+8)(-1w+8)=0

We multiply parentheses ..

8(-1w^2+8w-8w+64)=0

We multiply parentheses

-8w^2+64w-64w+512=0

We add all the numbers together, and all the variables

-8w^2+512=0

a = -8; b = 0; c = +512;
Δ = b2-4ac
Δ = 02-4·(-8)·512
Δ = 16384
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16384}=128$
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-128}{2*-8}=\frac{-128}{-16}
=+8
$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+128}{2*-8}=\frac{128}{-16}
=-8
