(x^(2)-64)/(8-x)
The binomial can be factored using the difference of squares formula, because both terms are perfect squares. The difference of squares formula is a^(2)-b^(2)=(a-b)(a+b).
((x-8)(x+8))/(-x+8)
Factor the expression.
((-1)(-x+8)(x+8))/(-x+8)
Reduce the expression by canceling out the common factor of (x-8) from the numerator and denominator.
((-1)(x-8)(x+8))/(-x+8)
Reduce the expression by canceling out the common factor of (x-8) from the numerator and denominator.
(-1)(x+8)
Multiply each term in the first polynomial by each term in the second polynomial.
(-1*x-1*8)
Multiply -1 by each term in x+8 to get -x-8.
(-x-8)
Remove the parentheses around the expression -x-8.
-x-8
