(2xy - yz + 3xz) - (6yz + 15x² - 4xy)= 2xy - yz + 3xz - 6yz - 15x² + 4xy
= -15x² + 2xy + 4xy - yz - 6yz + 3xz
= -15x² + 6xy - 7yz + 3xz

Saya coba bantu jawab yah !Penyelesaian :
--------------------
Kumpulkan variabel yang sama
(2xy - yz + 3xz) - (6yz + 15x² - 4xy)
= 2xy - yz + 3xz - 6yz - 15x² + 4xy
= 2xy + 4xy - yz - 6yz + 3xz - 15x²
= 6xy - 7yz + 3xz - 15x²
atau
= -15x² + 6xy + 3xz - 7yz
