Question

Which polynomials are in standard form?

x^2y^3 + y + 3xy^2

– 5a^3 + 12a^2b – 15ab^2 + b3

4xy + 2x^2y^2 + xy^3 <-- I think this one

7x4 + 4x3y – 3x2y2 – y4

14b^3 + ab^3 – 6ab + 8ab^2 <-- I think this one

3a^4 + 4a^3b – 6a^2b^2 – 4ab^3 – b^4

Answer 1

3a^4 + 4a^3b – 6a^2b^2 – 4ab^3 – b^4 is the answer :)

Answer 2

4xy + 2x^2y^2 + xy^3 this is not correct?

Answer 3

Well that is correct too...if we are to write the degrees in the descending order
Can ya have more than 1 correct answers?

Answer 4

yeah

Answer 5

7x4 + 4x3y – 3x2y2 – y4
– 5a^3 + 12a^2b – 15ab^2 + b3
4xy + 2x^2y^2 + xy^3
7x4 + 4x3y – 3x2y2 – y4
3a^4 + 4a^3b – 6a^2b^2 – 4ab^3 – b^4
would be the correct answers

Answer 6

3a^4 + 4a^3b – 6a^2b^2 – 4ab^3 – b^4 how would this be in correct order if the exponents are descending in correct order?

Answer 7

They all have the power 4
so technically they are also in the standard form

Answer 8

Look either you write it in the descending order or in the ascending order....
but what when they have the same degree?
They cannot be arranged n any other way and hence they are already in the standard form
Hope this helps :)

Answer 9

@vijeya3: thank you so much for these contributions, but could you please hold back a bit on offering direct answers. As you have already done, define "standard form" and then let the other person choose his or her answers. Thank you.

Answer 10

oh sorry...i thought that since it is an objective type question....we could give a direct one..
I apologize @mathmale :'(

Answer 11

Thank you again.
