0=x2+16
We move all terms to the left:
0-(x2+16)=0
We add all the numbers together, and all the variables
-(+x^2+16)+0=0
We add all the numbers together, and all the variables
-(+x^2+16)=0
We get rid of parentheses
-x^2-16=0
We add all the numbers together, and all the variables
-1x^2-16=0
a = -1; b = 0; c = -16;
Δ = b2-4ac
Δ = 02-4·(-1)·(-16)
Δ = -64
Delta is less than zero, so there is no solution for the equation
