Solution for 2(1/3)d=28 equation:



2(1/3)d=28
We move all terms to the left:
2(1/3)d-(28)=0
Domain of the equation: 3)d!=0
d!=0/1
d!=0
d∈R
We add all the numbers together, and all the variables
2(+1/3)d-28=0
We multiply parentheses
2d^2-28=0
a = 2; b = 0; c = -28;
Δ = b2-4ac
Δ = 02-4·2·(-28)
Δ = 224
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{224}=\sqrt{16*14}=\sqrt{16}*\sqrt{14}=4\sqrt{14}$
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{14}}{2*2}=\frac{0-4\sqrt{14}}{4} =-\frac{4\sqrt{14}}{4} =-\sqrt{14} $
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{14}}{2*2}=\frac{0+4\sqrt{14}}{4} =\frac{4\sqrt{14}}{4} =\sqrt{14} $
