x^2=x-72=0

We move all terms to the left:

x^2-(x-72)=0

We get rid of parentheses

x^2-x+72=0

We add all the numbers together, and all the variables

x^2-1x+72=0

a = 1; b = -1; c = +72;

Δ = b^{2}-4ac

Δ = -1^{2}-4·1·72

Δ = -287

Delta is less than zero, so there is no solution for the equation
