Question
Factorise the expression: $ax^2y + bxy^2+ cxyz$
✓
Answer
$ax^2y + bxy^2+ cxyz = a$
$ \times x \times x \times y + b \times x \times y \times y + c \times x \times y \times z$
Taking common factors from each term,
$= x \times y(a \times x + b \times y + c \times z)$
$= xy(ax + by + cz)$
$ \times x \times x \times y + b \times x \times y \times y + c \times x \times y \times z$
Taking common factors from each term,
$= x \times y(a \times x + b \times y + c \times z)$
$= xy(ax + by + cz)$
