3d/d=1d

Solution for 3d/d=1d equation:

3d/d=1d

We move all terms to the left:

3d/d-(1d)=0


Domain of the equation: d!=0

d∈R


We add all the numbers together, and all the variables

-1d+3d/d=0

We multiply all the terms by the denominator


-1d*d+3d=0

We add all the numbers together, and all the variables

3d-1d*d=0

Wy multiply elements

-1d^2+3d=0

a = -1; b = 3; c = 0;
Δ = b2-4ac
Δ = 32-4·(-1)·0
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-3}{2*-1}=\frac{-6}{-2}
=+3
$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+3}{2*-1}=\frac{0}{-2}
=0
