Question

1. The factorisation of x² y² + xy + xy²z + yz + x²yz + xz is ​

Answer 1

Answer:

SOLUTION

TO FACTORISE

x²y² + xy + xy²z + yz + x²yz + xz

EVALUATION

x²y² + xy + xy²z + yz + x²yz + xz

= x²y² + xy²z + x²yz + xy + yz + xz

= xy( xy + yz + xz ) + 1 ( xy + yz + xz )

= ( xy + 1 ) ( xy + yz + xz )
