Factor completely.
150m^2nz+20mn^2c-120m^2nc-25mn^2z

The factor form is:

Step-by-step explanation:

Here we have to find the factor of the expression:

So we need to take out the common terms, as we do for finding the greatest common factors.

Now the expression that is given can be re-written as:

Next, we will find the common terms, as follows;

Now  we will factorise the expression:

as follows;

So the final factor form is:

0 is its x and y coordinate
