n2+2n=5.424
We move all terms to the left:
n2+2n-(5.424)=0
We add all the numbers together, and all the variables
n^2+2n-5.424=0
a = 1; b = 2; c = -5.424;
Δ = b2-4ac
Δ = 22-4·1·(-5.424)
Δ = 25.696
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{-(2)-\sqrt{25.696}}{2*1}=\frac{-2-\sqrt{25.696}}{2} $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+\sqrt{25.696}}{2*1}=\frac{-2+\sqrt{25.696}}{2} $
