The Solving Quadratic Equations Using Patterns Quick Check

Solve the following quadratic equation using the perfect square trinomial pattern: x2-16x+64=0.

1 answer

To solve the quadratic equation \( x^2 - 16x + 64 = 0 \) using the perfect square trinomial pattern, we can first recognize that the left-hand side can be expressed as a square of a binomial.

The equation can be rewritten as:

\[ x^2 - 16x + 64 = (x - 8)^2 \]

This follows because:

\[ (x - 8)(x - 8) = x^2 - 8x - 8x + 64 = x^2 - 16x + 64 \]

Now, we can set the squared term equal to zero:

\[ (x - 8)^2 = 0 \]

To solve for \( x \), we take the square root of both sides:

\[ x - 8 = 0 \]

Adding 8 to both sides gives:

\[ x = 8 \]

Thus, the solution to the quadratic equation \( x^2 - 16x + 64 = 0 \) is:

\[ \boxed{8} \]
