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]
