Which terms could be used as the first term of the expression below to create a polynomial written in standard form? check all that apply.
+ 8r2s4 – 3r3s3
s5
3r4s5
–r4s6
–6rs5

Option 2,3 and 4 are correct.

Step-by-step explanation:

To find : Which terms could be used as the first term of the expression below to create a polynomial written in standard form? Check all that apply.

Solution :

The polynomials in standard form is written from higher degree to lower degree i.e. in descending order.

The given polynomial has degree 6: , and it can be ordered respect any of the two variables either r or s.

Adding a new term as first term needs to have degree equal or greater than 6.

1) cannot use as first term because its degree is less than 6.

2) it can be use as degree is 9.

is the standard form.

3) it can be use as degree is 10.

is the standard form.

4) it can be use as degree is 6.

is the standard form.

Therefore, Option 2,3 and 4 are correct.
