36=(x-1)(x+1)
We move all terms to the left:
36-((x-1)(x+1))=0
We use the square of the difference formula
x^2+1+36=0
We add all the numbers together, and all the variables
x^2+37=0
a = 1; b = 0; c = +37;
Δ = b2-4ac
Δ = 02-4·1·37
Δ = -148
Delta is less than zero, so there is no solution for the equation
