(8x-4)*(2x-2)=0

Solution for (8x-4)*(2x-2)=0 equation:

(8x-4)(2x-2)=0

We multiply parentheses ..

(+16x^2-16x-8x+8)=0

We get rid of parentheses

16x^2-16x-8x+8=0

We add all the numbers together, and all the variables

16x^2-24x+8=0

a = 16; b = -24; c = +8;
Δ = b2-4ac
Δ = -242-4·16·8
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-8}{2*16}=\frac{16}{32}
=1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+8}{2*16}=\frac{32}{32}
=1
