Answer 1

Resposta:

$a) \: 1 - {y}^{2} \\ (1 - y) \times (1 + y)$

$b) \: {m}^{2} - {n}^{2} \\ (m - n) \times (m + n)$

$c) \: 9 - {x}^{2} \\ (3 - x) \times (3 + x)$

$d) \: {x}^{2} - 1 \\ (x - 1) \times (x + 1)$

$e) \: {x}^{2} - {a}^{2} \\ (x - a) \times (x + a)$

$f) \: 1 - 49 {a}^{2} \\ (1 - 7a) \times (1 + 7a)$

$g) \: 6x + 6y + ax + y \\ 6x + ax + 7y \\ x \times (6 + a) + 7y$

$h) \: ax + ay + 7x + 7y \\ a \times (x + y) + 7 \times (x + y)$

$i) \: 2a + 2m + ax + ay \\ 2 \times (a + m) + a \times (x + y)$

$j) \: 3a - 3b + ax + bx \\ 3 \times (a - b) + x \times (a + b)$

$k) \: 7ax - 7a + bx \\ 7a \times (x - 1) + bx$

$l) \: 2x - 2 + yx - y \\ 2 \times (x - 1) + y \times (x - 1)$

$m) \: {x}^{2} \times (x - 1) + x - 1 \\ (x - 1) \times ( {x}^{2} + 1)$

$n) \: {x}^{3} - 5 {x}^{2} + 4x - 20 \\ {x}^{2} \times (x - 5) + 4 \times (x - 5) \\ (x - 5) \times ( {x}^{2} + 4)$
