Question

What is true about the sum of the two polynomials? 6s2t – 2st2 4s2t – 3st2

Answer 1

Answer:

The sum is 10s^2t-5st^2.  With two separate sections, it is a binomial, and since the sum of the powers of the variables is 2+1=3, it has a degree of 3.  B is the correct answer.

Step-by-step explanation:

Answer 2

We recall the concept of polynomial

Polynomial: It is defined as an expression that is composed of variables, constants, and exponents

Given:

Two polynomials,$6s^{2} t-2st^{2} ,4s^{2} t-3st^{2}$

Adding two polynomials,

$6s^{2} t-2st^{2} +4s^{2} t-3st^{2}=6s^{2} t+4s^{2} t-2st^{2}-3st^{2}$[Combining like terms}

                                       $=10s^{2}t-5st^{2}$

The sum of two polynomials is    $10s^{2}t-5st^{2}$
