To solve the quadratic equation \(x^2 - 16x + 64 = 0\) using the perfect square trinomial pattern, we recognize that the equation can be factored as:
\[ (x - 8)^2 = 0 \]
Next, we take the square root of both sides:
\[ x - 8 = 0 \]
Now, we solve for \(x\):
\[ x = 8 \]
So, the solution to the equation is:
x = 8 (Option: x equals 8)
