How do I simplify 6x^2 + y - x^2 + 5 + x - 3y^2

### 2 Answers | Add Yours

This can't be simplified much. The only like terms are the two terms with x^2.

**6x^2** + y **- x^2** + 5 + x - 3y^2

So, you can simplify to 5x^2 + y + 5 + x - 3y^2, but I don't see how you can simplify it any further.

### 6x^2 + y - x^2 + 5 + x - 3y^2.

To simplify the above:

There are 6 terms, separated by a ** +** or **- **signs.

Group like terms along with their signs:

**6x^2-x^2** + x + y-3y^2 + 5 (1)

Now 6x^2-x^2=5x^2. Replace accordingly.

**5x^2+x **-3y^2+y** + 5**. This is simlified form.

For the sake of order, but not necessary, the x's and y's are kept in a descending order and then constant term.
