0=n^2-16n+93
We move all terms to the left:
0-(n^2-16n+93)=0
We add all the numbers together, and all the variables
-(n^2-16n+93)=0
We get rid of parentheses
-n^2+16n-93=0
We add all the numbers together, and all the variables
-1n^2+16n-93=0
a = -1; b = 16; c = -93;
Δ = b2-4ac
Δ = 162-4·(-1)·(-93)
Δ = -116
Delta is less than zero, so there is no solution for the equation
