d2+37d=0

Solution for d2+37d=0 equation:

d2+37d=0

We add all the numbers together, and all the variables

d^2+37d=0

a = 1; b = 37; c = 0;
Δ = b2-4ac
Δ = 372-4·1·0
Δ = 1369
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1369}=37$
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(37)-37}{2*1}=\frac{-74}{2}
=-37
$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(37)+37}{2*1}=\frac{0}{2}
=0
