Indicate the sum of the terms in each of the following examples, and simplify the result by combining like terms:

10r2, −6r, +5s, −8r, +2s, −5r2, −4s what is the value of this expression for r=1, s=3

The sum of the terms is equal to .

The value of the sum at is 0.

Step-by-step explanation:

Given:

The terms that are given are:

The sum of the terms is the addition of the given terms and is given as:

Now, combining like terms. Like terms means that are of the same type are grouped together. There are 3 different terms here 'r²', 'r' and 's'.

The terms containing 'r²' are:

The terms containing 'r' are:

The terms containing 's' are:

Now, combining the like terms, we get:

Therefore, the final expression is equal to:

Now, plug in . This gives,

Therefore, the value of the sum of all the terms at is 0.
