x^2+3x=16384

Solution for x^2+3x=16384 equation:

x^2+3x=16384

We move all terms to the left:

x^2+3x-(16384)=0

a = 1; b = 3; c = -16384;
Δ = b2-4ac
Δ = 32-4·1·(-16384)
Δ = 65545
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-\sqrt{65545}}{2*1}=\frac{-3-\sqrt{65545}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{65545}}{2*1}=\frac{-3+\sqrt{65545}}{2}
