Question

a)6x+6y+ax+ay b)ax+ay+7x+7y c)2a+2n+ax+nx d)ax+5bx+ay+5by

Answer 1

a
6x + 6y + ax + ay =
6 ( x + y) + a ( x + y)=
( x + y) ( 6 + a)
b
ax + ay + 7x + 7y =
a( x + y) + 7 ( x + y) = 
( a + 7) ( x + y)
c
2a + 2n + ax + nx =
2( a + n) + x ( a + n) =
( 2 + x) ( a + n)
d
 ax + 5bx + ay + 5by =
x ( a + 5b) + y ( a + 5b) =
( x + y) ( a + 5b)

Answer 2

Oie, Td Bom?!

a)

$= 6x + 6y + ax + ay$

$= 6(x + y) + a \: . \: (x + y)$

$= (x + y) \: . \: (6 + a)$

b)

$= ax + ay + 7x + 7y$

$= a \: . \: (x + y) + 7(x + y)$

$= (x + y) \: . \: (a + 7)$

c)

$= 2a + 2n + ax + nx$

$= 2(a + n) + x \: . \: (a + n)$

$= (a + n) \: . \: (2 + x)$

d)

$= ax + 5bx + ay + 5by$

$= x \: . \: (a + 5b) + y \: . \: (a + 5b)$

$= (a + 5b) \: . \: (x + y)$
