Answer 1

Oie, Td Bom?!

A)

$= (t - 7) {}^{2}$

$= t {}^{2} - 2t \: . \: 7 + 7 {}^{2}$

$= t {}^{2} - 14t + 49$

B)

$= (10 + w) \: . \: (10 - w)$

$= 10 {}^{2} - w {}^{2}$

$= 100 - w {}^{2}$

C)

$= (12 - h) {}^{2}$

$= 12 {}^{2} - 2 \: . \: 12h + h {}^{2}$

$= 144 - 24h + h {}^{2}$

$= h {}^{2} - 24h + 144$

D)

$= (11 + n) {}^{2}$

$= 11 {}^{2} + 2 \: . \: 11n + n {}^{2}$

$= 121 + 22n + n {}^{2}$

$= n {}^{2} + 22n + 121$

E)

$= (13 + j) \: . \: (13 - j)$

$= 13 {}^{2} - j {}^{2}$

$= 169 - j {}^{2}$
