Question

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

Answer 1

This is the simplified expression, if that's what you're asking for: 5x^2 - 7x + 15.

Answer 2

The answer is
`5x^2-7x+15`

Explanation:

In order to determine the final expression, we have to know about adding similar terms.

When we add similar terms, firstly we have to find the amount of different terms. A term is basically the variable and its power.

In this case, there are 3 terms:

1. 
   `x^2`
2. 
   `x`
3. 
   `number`

Then, we add similar terms:

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

Finally, the final expression is
`5x^2-7x+15`
