4j*8j=8

Solution for 4j*8j=8 equation:

4j*8j=8

We move all terms to the left:

4j*8j-(8)=0

Wy multiply elements

32j^2-8=0

a = 32; b = 0; c = -8;
Δ = b2-4ac
Δ = 02-4·32·(-8)
Δ = 1024
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$j_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$j_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1024}=32$
$j_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-32}{2*32}=\frac{-32}{64}
=-1/2
$
$j_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+32}{2*32}=\frac{32}{64}
=1/2
