Answer 1

Respuesta:

$a)(m + 2)(m - 2) = {m}^{2} - 4$

$b)(a - 1)(a + 1) = {a}^{2} -1$

$c) {(m - 2)}^{2} = {m}^{2} + 4 - 4m$

$d) {(a + 5)}^{2} = {a}^{2} + 25 + 10a$

$e)(x + 5)(x - 5) = {x}^{2} - 25$

$f) {(m + 4)}^{2} = {m}^{2} + 16 + 8m$

Explicación

${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab$

${(a - b)}^{2} = {a}^{2} + {b}^{2} - 2ab$

$(a + b)(a - b) = {a}^{2} - {b}^{2}$
