Answer:
The multiple zero is
.
The multiplicity is 2
Step-by-step explanation:
The given function is

To find the zero of this function, we equate it to zero.

We factor to obtain;

Observe that; the expression within the parenthesis is a perfect square.
This implies that;

This implies that;
Either
or 
has a multiple zero which is
and its multplicity is 2.
It states your "X" will be zero when solving for "Y".
So when solving for "Y" your equation would be;
0+y=4
Then you solve. Y=4
Then you do the same with the "X":
X+0=4. Then you solve. X=4
It would end up being (4(x),4(y) )
Then do the same for the next problem.
