(2s + 5z)^2 * (s + 3z)^2
2s+5z
2s+5z now multiply
----------
4s^2+10sz+10sz+25z^2
4s^2+20sz+25z^2
-------------
s+3z
s+3z now multiply
-----
s^2+3sz+3sz+9z^2
s^2+6sz+9z^2
4s^2+20sz+25z^2 now multiply.
----------------
4s^4+24s^3z+36s^2z^2+20s^3z+120s^2z^2+180sz^3+25sz^2+150sz^3+225z^4
4s^4+44s^3z+156s^2z^2+330sz^3+225z^4 ans.
