Final answer:
To factor the expression m2 - 49, which is a difference of two squares, identify the square terms m^2 and 7^2 and factor them into (m + 7)(m - 7).
Step-by-step explanation:
The question is about factoring the expression m2 - 49, which is a difference of two squares. In algebra, a difference of two squares is a binomial of the form a^2 - b^2 and it can be factored into (a + b)(a - b). In the given expression, m2 represents a^2, and 49, which is 7^2, represents b^2.
To factor m2 - 49, you identify the squares as m^2 and 7^2, and then write the factors as (m + 7)(m - 7). Therefore, the factored form of m2 - 49 is (m + 7)(m - 7).
