Question

Perform the operation indicated, then place the answer in the proper location on the grid. Write your answer in descending powers of x. (6x 2 - 4x + 11) + ( 4 - x 2 - 3x)

Answer 1

The answer after performing the indicated operation is in descending powers of x is
`5x^2-7x+15`

Explanation:

Given expression is
`(6x^2-4x+11)+(4-x^2-3x)`

To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:

Now solve the given expression as below ( that is perform the operation indicated)

`(6x^2-4x+11)+(4-x^2-3x)`

`=6x^2-4x+11+4-x^2-3x`

Adding the like terms we get

`=5x^2-7x+15`

`(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15`

The answer after performing the indicated operation is in descending powers of x is
`5x^2-7x+15`
