Question

xy^2z^2 + 3x^2y^2z - 4x^2yz^2, - 9x^2y^2z + 3xy^2z^2 + x^2 yz^2

Answer 1

Answer:

4xy^2 z^2 −6x^2 y^2 z−3x^2 z^2

Step-by-step explanation:

xy ^2 z^2 +3x^2 y^2z−4x^2 yz^2 +−9x^2 y^2 z+3xy ^2 z^2 +x^2 yz^2

=xy^2 z^2 −4x^2 yz^2 +3x^2y ^2 z+x^2 yz^2 −4x^2 yz^2 −9x^2 y^2 z

=4xy^2 z^2 −6x^2 y^2 z−3x^2 z^2
