n2-3n-1000=0
We add all the numbers together, and all the variables
n^2-3n-1000=0
a = 1; b = -3; c = -1000;
Δ = b2-4ac
Δ = -32-4·1·(-1000)
Δ = 4009
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}$$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-3)-\sqrt{4009}}{2*1}=\frac{3-\sqrt{4009}}{2} $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3)+\sqrt{4009}}{2*1}=\frac{3+\sqrt{4009}}{2} $
