Answer:
x = 6
Step-by-step explanation:
Start off by reducing this equation: divide all three terms by 4. This yields:
x^2 - 12x + 36 = 0
This equation has the form (x - h)^2, the square of a binomial.
x^2 - 12x + 36 = 0, written as the square of the binomail x - 6, comes out to:
(x - 6)^2 = 0. This equation has a repeated real root: x = 6
