Question

Write the expression in factored form. m^2-4

Answer 1

(m-2)(m+2)

Explanation:

a²-b²=(a-b)(a+b)

let m be a and 2 be b

m^2-2²=(m-2)(m+2)

Answer 2

For this case we must factor the following expression:

`m ^ 2-4`

According to the formula of difference of squares we have:

`a ^ 2-b ^ 2 = (a + b) (a-b)`

We have to:

`a = m\\b = 2`

So, we have:

`m ^ 2-4 = (m + 2) (m-2)`

Answer:

The factored expression is:
`m ^ 2-4 = (m + 2) (m-2)`
