We add all the numbers together, and all the variables

48d/18d^2+(-15d)/18d^2-21=0

We multiply all the terms by the denominator


48d+(-15d)-21*18d^2=0

Wy multiply elements

-378d^2+48d+(-15d)=0

We get rid of parentheses

-378d^2+48d-15d=0

We add all the numbers together, and all the variables

-378d^2+33d=0

a = -378; b = 33; c = 0;
Δ = b2-4ac
Δ = 332-4·(-378)·0
Δ = 1089
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1089}=33$
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(33)-33}{2*-378}=\frac{-66}{-756}
=11/126
$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(33)+33}{2*-378}=\frac{0}{-756}
=0
