0=n^2+75
We move all terms to the left:
0-(n^2+75)=0
We add all the numbers together, and all the variables
-(n^2+75)=0
We get rid of parentheses
-n^2-75=0
We add all the numbers together, and all the variables
-1n^2-75=0
a = -1; b = 0; c = -75;
Δ = b2-4ac
Δ = 02-4·(-1)·(-75)
Δ = -300
Delta is less than zero, so there is no solution for the equation
