Question

X2/y+x2/ for x=6,y=-4 and z=-2

Answer 1

x2/y+x2/
x=6
y=-4
z=-2

6✖️2/-4➕6✖️2
6✖️2=12
This goes for both due to PEMDAS
Now it looks like this:
12/-4➕12

-4➕12= 8

Now it looks like this:
12/8

Since there was no z then -2 wouldn’t be needed

So your answer would be 12/8

Hope this helps! :3
