(n+4)+n(n+2)+n=0n
We move all terms to the left:
(n+4)+n(n+2)+n-(0n)=0
We add all the numbers together, and all the variables
(n+4)+n(n+2)=0
We multiply parentheses
n^2+(n+4)+2n=0
We get rid of parentheses
n^2+n+2n+4=0
We add all the numbers together, and all the variables
n^2+3n+4=0
a = 1; b = 3; c = +4;
Δ = b2-4ac
Δ = 32-4·1·4
Δ = -7
Delta is less than zero, so there is no solution for the equation
