0=K2-
We move all terms to the left:
0-(K2-)=0
We add all the numbers together, and all the variables
-(+K^2-)+0=0
We add all the numbers together, and all the variables
-(+K^2-)=0
We get rid of parentheses
-K^2+=0
We add all the numbers together, and all the variables
-1K^2=0
a = -1; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-1)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
