p2+38p=0

Solution for p2+38p=0 equation:

p2+38p=0

We add all the numbers together, and all the variables

p^2+38p=0

a = 1; b = 38; c = 0;
Δ = b2-4ac
Δ = 382-4·1·0
Δ = 1444
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1444}=38$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(38)-38}{2*1}=\frac{-76}{2}
=-38
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(38)+38}{2*1}=\frac{0}{2}
=0
