Question

3- Fatore utilizando agrupamento: a) a2 + ab + ax + bx = b) ax – bx + ay -by =

Answer 1

Explicação passo-a-passo:

a)

a² + ab + ax + bx

= a.(a + b) + x.(a + b)

= (a + b).(a + x)

b)

ax - bx + ay - by

= x.(a - b) + y.(a - b)

= (a - b).(x + y)

Answer 2

Oie, Td Bom?!

a)

$= a {}^{2} + ab + ax + bx$

$= a \: . \: (a + b) + x \: . \: (a + b)$

$= (a + b) \: . \: (a + x)$

b)

$= ax - bx + ay - by$

$= x \: . \: (a - b) + y \: . \: (a - b)$

$= (a - b) \: . \: (x + y)$
