To solve the quadratic equation \( x^2 - 16x + 64 = 0 \) using the perfect square trinomial pattern, we first recognize that the left side can be factored.
The general form of a perfect square trinomial is \( (x - a)^2 = 0 \). In this case, we can see that:
\[ x^2 - 16x + 64 = (x - 8)^2 \]
So we rewrite the equation:
\[ (x - 8)^2 = 0 \]
Now, we can take the square root of both sides:
\[ x - 8 = 0 \]
Solving for \( x \):
\[ x = 8 \]
Thus, the solution to the equation \( x^2 - 16x + 64 = 0 \) is:
x = 8
So the correct response is:
x=8
