Respuesta :

4b^2 - 16 =
4(b^2 - 4) =
4(b + 2)(b - 2)

Answer:

[tex]4(b+2)(b-2)[/tex]

Step-by-step explanation:

We have been given an expression and we are asked to find the factors of our given expression.

[tex]4b^2-16[/tex]

First of all we will factor out 4 from our given expression.

[tex]4(b^2-4)[/tex]

We can see that [tex]b^2-4[/tex] is difference of squares, so we can factor it using difference of squares formula: [tex]a^2-b^2=(a+b)(a-b)[/tex].

[tex]4(b^2-2^2)[/tex]

[tex]4(b+2)(b-2)[/tex]

Therefore, the factored form of our given expression is [tex]4(b+2)(b-2)[/tex].
