8x(-1+2x)=)

Solution for 8x(-1+2x)=) equation:

8x(-1+2x)=)

We move all terms to the left:

8x(-1+2x)-())=0

We add all the numbers together, and all the variables

8x(2x-1)-())=0

We add all the numbers together, and all the variables

8x(2x-1)=0

We multiply parentheses

16x^2-8x=0

a = 16; b = -8; c = 0;
Δ = b2-4ac
Δ = -82-4·16·0
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{-(-8)-8}{2*16}=\frac{0}{32}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-8)+8}{2*16}=\frac{16}{32}
=1/2
