A. 2x^3y + 7y^2x - 3x^2 - 12y

cggurumanjunath · Answer

look at the powers say in first term 2x^3y the combined power is 4 
then next term it is 3

agent0smith · Answer

Yep, arrange terms in order of degree (xy^2 would be of degree 3, since you'd add the total exponents)

cggurumanjunath · Answer

the power keeps on decreasing .

cggurumanjunath · Answer

hence a is in standard form
