x2=-11+6x
We move all terms to the left:
x2-(-11+6x)=0
We add all the numbers together, and all the variables
x2-(6x-11)=0
We add all the numbers together, and all the variables
x^2-(6x-11)=0
We get rid of parentheses
x^2-6x+11=0
a = 1; b = -6; c = +11;
Δ = b2-4ac
Δ = -62-4·1·11
Δ = -8
Delta is less than zero, so there is no solution for the equation
