Order the polynomial -x 4 y 2 + 7x 3 y 3 - 3xy 5 + 2x 2 y 4 in descending powers of x.
bulgar [2K]

put all the combos together first like -3xy

then the x's like -x + 7x +2x=8x

then the y's

then the whole numbers

-3xy+8x (then the y's) then the whole numbers.

I am not sure how you are writing the numbers above like -x 4 is that -x to the 4th power?

x^4 then the x^3 and so forth then the y's then the whole numbers.

Always start adding the highest x power numbers first like x^4 + 2x^4=3x^4 then work your way down. Maybe rewrite the problem please.
