1/4k-16-(12k)=0
Domain of the equation: 4k!=0
k!=0/4
k!=0
k∈R
We add all the numbers together, and all the variables
-12k+1/4k-16=0
We multiply all the terms by the denominator
-12k*4k-16*4k+1=0
Wy multiply elements
-48k^2-64k+1=0
a = -48; b = -64; c = +1;
Δ = b2-4ac
Δ = -642-4·(-48)·1
Δ = 4288
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{4288}=\sqrt{64*67}=\sqrt{64}*\sqrt{67}=8\sqrt{67}$
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-64)-8\sqrt{67}}{2*-48}=\frac{64-8\sqrt{67}}{-96} $
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-64)+8\sqrt{67}}{2*-48}=\frac{64+8\sqrt{67}}{-96} $
