Question
Factorise the expression: $x^2yz + xy^2z + xyz^2$
✓
Answer
$x^2yz + xyz + xyz^2= x\times x \times y \times z + x \times y \times y \times z + x \times y \times z \times z$
Taking common factors from each term,
$= x \times y \times z(x + y + z)$
$= xyz(x + y + z)$
Taking common factors from each term,
$= x \times y \times z(x + y + z)$
$= xyz(x + y + z)$

Stretching Machine:
Suppose you have a stretching machine which could stretch almost anything. For example, if you put a $5$ metre stick into a $(×4)$ stretching machine (as shown below), you get a $20$ metre stick. Now if you put $10\ cm$ carrot into a $(\times 4)$ machine, how long will it be when it comes out?
