g=−3w 4 +2w 2 z 2 +5z 4 p=8w 4 −3w 2 z 2 +z 4 p-g=p−g=p, minus, g, equals your answer should be a polynomial in standard form.

Please take the time to type in the question by yourself.  I assume you use some kind of an apps to transcribe problems.  It only confuses and discourages helpers.  The fact that the question was reported means it is not clear.

I ASSUME the question is as follows:


Need to find P-G.

We see clearly that each expression P, G contains 3 terms, namely w^4, w^2z^2 and z^4.  We will have to add/subtract like terms to get the answer.


 (distribute negative sign into expression G)
 (group like terms)
 (add/subtract like terms)

The reporter forgot to multiply the decimal by 100, making it 25%
