Question

factorise the following:m²-121

​

Answer 1

Answer:

(m - 11) (m + 11)

Step-by-step explanation:

m² - 121

= m² - 11²

= (m - 11) (m + 11)

by using a² - b² = (a - b)( a + b)

hope this helps you dear..

Answer 2

Answer:

m²-121:

(a−b)(a+b)=a² −b²

m  ² −121= (m−11)(m+11)

The factors are m−11,m+11.
