Question 1151789
<pre>
Maybe some other tutor has a different idea on this. What do you say, Ikleyn?
greenestamps? josgarithmetic? jim_thompson5910? MathLover1?


Marcus states that the polynomial expression 
{{{3x^3-4x^2y + y^3 + 2}}} 
is in standard form. Ariel states that it should be 
{{{y^3-4x^2y+3x^3+2}}}. Explain which student is correct and why.
<pre>
At first, I would have said both are correct.
Marcus has the polynomial in descending powers of x.
Ariel has put the polynomial in descending powers of y. 

However I think Marcus should have made the second term -4yx², not -4x²y,
because each term should end with the power of the letter which the
polynomial expression is in descending powers of.
