Sagot :
Factor the numerator : m² - 81
The factors are: (m-9) (m+9)
m² - 81
m+9
(m-9) (m+9) = m-9
(m+9)
Final answer : m-9
The factors are: (m-9) (m+9)
m² - 81
m+9
(m-9) (m+9) = m-9
(m+9)
Final answer : m-9
Factor the numerator as (m+9) (m-9)
Since there is (m+9) in the denominator, cancel both
So the answer is (m-9)
Since there is (m+9) in the denominator, cancel both
So the answer is (m-9)
