n-n2=-60
We move all terms to the left:
n-n2-(-60)=0
We add all the numbers together, and all the variables
-1n^2+n+60=0
a = -1; b = 1; c = +60;
Δ = b2-4ac
Δ = 12-4·(-1)·60
Δ = 241
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{-(1)-\sqrt{241}}{2*-1}=\frac{-1-\sqrt{241}}{-2} $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{241}}{2*-1}=\frac{-1+\sqrt{241}}{-2} $
