133=(x+6)(x-6)
We move all terms to the left:
133-((x+6)(x-6))=0
We use the square of the difference formula
x^2+36+133=0
We add all the numbers together, and all the variables
x^2+169=0
a = 1; b = 0; c = +169;
Δ = b2-4ac
Δ = 02-4·1·169
Δ = -676
Delta is less than zero, so there is no solution for the equation
