Hi, I'm in Year 8 (Australia) so this should be an easy question for
you guys seeing what this group is about... but how do you 'fully
factorise' this?

(They've given me the identities: difference of two squares, sum and
difference of two cubes and the perfect square rule but I'm not sure
how you apply them; i can do the individual questions relating to each
one of these indentities, but then again this question is in the
'problems section' [the last question] of this booklet...)

a²b² -a² -b² + 1

Hint:

First try 2 simpler problems:

(1) Factor: uv + u + v + 1

(2) Factor: uv - u - v + 1
