Write a quadratic equation with a solution of x = 8

How do you write a quadratic equation with a solution of x = 8?

Just work backwards from the solution:

x = 8
x - 8 = 0 or x - 8 = 0   {two equations that would yield 8 for a solution}
(x - 8)(x - 8) = 0   {put the two binomials together on the same side}
x² - 16x + 64 = 0   {used foil method to get the quadratic equation}
