How to combine terms for a truth table containing two outputs

Question

here's my truth table:

A   B   C   D   Z1  Z2
0   0   0   0   0   0
0   0   0   1   1   0
0   1   0   0   0   0
0   0   1   1   1   0
0   1   0   0   0   1
0   1   0   1   1   1
0   1   1   0   0   1
0   1   1   1   0   0
1   0   0   0   0   0
1   0   1   1   1   0
1   1   0   0   0   1
1   1   0   1   0   0
1   1   1   0   0   1
1   1   1   1   1   1

How do I combine each single row's boolean expression for Z1 and Z2 into a larger term? And can you please provide a direct example of how to do it? Thanks!
