3) (x + 8) . (x - 8) =

4) (x + 24) . (x - 24) =

5) (x +1) . (x - 1) =

6) (x + 18) . (x - 18) =

Answer 1

Resposta:

Explicação passo a passo:

1) (x + 13) . (x - 13)

= x^2 - 13^2

= x^2 - 169

2) (x + 20) . (x - 20)

= x^2 - 20^2

= x^2 - 400

3) (x + 8) . (x - 8)

= x^2 - 8^2

= x^2 - 64

4) (x + 24) . (x - 24)

= x^2 - 24^2

= x^2 - 576

5) (x +1) . (x - 1)

= x^2 - 1^2

= x^2 - 1

6) (x + 18) . (x - 18)

= x^2 - 18^2

= x^2 - 324
