Answer:
a=x and b=9
(x+9)(x−9)
Explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b)
The answer to your question is (x+9)(x-9)
Step-by-step explanation:
Rewrite 81 as 92
x2−92
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b)
where a=x and b=9
(x+9)(x−9)
Hope this helped you out:)
