Question

Fatorando 5x + 5y + 5z – ax – ay – az, obtemos?

a) (x – y – z)(5 + a)

b) (x + y + z)(5 – a)

c) (x + y + z)(5 + a)

d) (x – y – z)(5 – a)​

Answer 1

$5x + 5y + 5z - ax - ay - az$

$5(x + y + z) - a(x + y + z)$

$(5 - a) (x + y + z)$

$(x + y + z) \times (5 - a)$

$\boxed{\boxed{\boxed{\sf \: b) \: (x + y + z) \times (5 - a)\: }}}$
