Question

4(x-y)(x-y)-12(x-y)(z)+9zx

Answer 1

Step-by-step explanation:

Let's simplify step-by-step.

4(x−y)(x−y)−12(x−y)z+9zx

Distribute:

=(4(x−y))(x)+(4(x−y))(−y)+−12xz+12yz+9zx

=4x2+−4xy+−4xy+4y2+−12xz+12yz+9xz

Combine Like Terms:

=4x2+−4xy+−4xy+4y2+−12xz+12yz+9xz

=(4x2)+(−4xy+−4xy)+(−12xz+9xz)+(4y2)+(12yz)

=4x2+−8xy+−3xz+4y2+12yz

Answer:

=4x2−8xy−3xz+4y2+12yz
