Solution for 54n^2+78n=0 equation:



54n^2+78n=0
a = 54; b = 78; c = 0;
Δ = b2-4ac
Δ = 782-4·54·0
Δ = 6084
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{6084}=78$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(78)-78}{2*54}=\frac{-156}{108} =-1+4/9 $
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(78)+78}{2*54}=\frac{0}{108} =0 $
