X2+168=-1X
We move all terms to the left:
X2+168-(-1X)=0
We add all the numbers together, and all the variables
X^2-(-1X)+168=0
We get rid of parentheses
X^2+1X+168=0
We add all the numbers together, and all the variables
X^2+X+168=0
a = 1; b = 1; c = +168;
Δ = b2-4ac
Δ = 12-4·1·168
Δ = -671
Delta is less than zero, so there is no solution for the equation
