3n2-7n-880=0

Solution for 3n2-7n-880=0 equation:

3n^2-7n-880=0

a = 3; b = -7; c = -880;
Δ = b2-4ac
Δ = -72-4·3·(-880)
Δ = 10609
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{10609}=103$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-7)-103}{2*3}=\frac{-96}{6}
=-16
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+103}{2*3}=\frac{110}{6}
=18+1/3
