Chapter 6: Q. 191 (page 603)

In the following exercises, factor completely using the difference of squares pattern, if possible.
$x^{2} - 16 x + 64 - y^{2}$

Short Answer

Expert verified

The factored form of the given expression is $(x - 8 - y) (x - 8 + y)$ .

Step by step solution

Step 1. Given information.

The given expression is:

$x^{2} - 16 x + 64 - y^{2}$

Step 2. Determine the factored form.

The given expression can be written as:

$\begin{array}{rcl} x^{2} - 16 x + 64 - y^{2} & = & x^{2} - 2 (x) (8) + 8^{2} - y^{2} \\ = & {(x - 8)}^{2} - y^{2} [∵ {(a - b)}^{2} = a^{2} - 2 a b + b^{2}] \\ = & (x - 8 - y) (x - 8 + y) [∵ {a^{2} - b}^{2} = (a - b) (a + b)] \end{array}$

Step 3. Conclusion.

The factored form of the given expression is $(x - 8 - y) (x - 8 + y)$ .
