Question

What is true about the sum of the two polynomials ? 6s^2t-2st^2 and 4s^2t- 3st^2? The sum of a binomial is 2 . the sum of a binomial is 3 . the sum of a trinomial is 2 . the sum of a trinomial is 3.

Answer 1

Answer:B

Explanation:

got it right

Answer 2

A. The sum of binomial is 2.

Explanation:

We are given that two polynomials

`6s^2t-2st^2`

`4s^2t-3st^2`

We have to find the sum of the two polynomials

Let
`p=6s^2t-2st^2`

`q=4s^2t-3st^2`

Adding two polynomials then we get

`p+q=6s^2t-2st^2+4s^2t-3st^2`

`p+q=6s^2t+4s^2t-2st^2-3st^2`

`p+q=(6+4)s^2t-(2+3)st^2`

By taking common
`s^2t` from
`6s^2t\;and\; 4s^2t`

and
`st^2` from
`2st^2` and
`3st^2`

Therefore, we have sum two polynomials

`p+q=10s^2t-5st^2`

Binomial means the polynomial contains two terms

Therefore, the sum of binomial is '2'.

Hence , option A is true.

A. The sum of binomial is 2.
