Answer:
(m-2)(m+2)
Step-by-step explanation:
a²-b²=(a-b)(a+b)
let m be a and 2 be b
m^2-2²=(m-2)(m+2)
For this case we must factor the following expression:
[tex]m ^ 2-4[/tex]
According to the formula of difference of squares we have:
[tex]a ^ 2-b ^ 2 = (a + b) (a-b)[/tex]
We have to:
[tex]a = m\\b = 2[/tex]
So, we have:
[tex]m ^ 2-4 = (m + 2) (m-2)[/tex]
Answer:
The factored expression is:[tex]m ^ 2-4 = (m + 2) (m-2)[/tex]
