3x2 - 5x+1

2x2 +9x-6

as

3x^2 - 5x+1

2x^2 +9x-6 " ^ " indicates exponentiation

-----------------

5x^2 + 4x - 5

Answer 2

`5x^2+4x-5`

Explanation:

`3x^2-5x+1 \ and \ 2x^2 + 9x -6`

Add both the polynomials

To add both the polynomials we combine like terms

`3x^2-5x+1 +2x^2 + 9x -6`

3x^2 and 2x^2 are like terms . it becomes 5x^2

-5x and 9x are like terms . it becomes 4x

`3x^2-5x+1 +2x^2 + 9x -6`
