Answer:
The sum of the two expressions is 5x^2 + 4x - 5
Step-by-step explanation:
Rewrite
3x2 - 5x+1
2x2 +9x-6
as
3x^2 - 5x+1
2x^2 +9x-6 " ^ " indicates exponentiation
-----------------
5x^2 + 4x - 5
Answer:
[tex]5x^2+4x-5[/tex]
Step-by-step explanation:
[tex]3x^2-5x+1 \ and \ 2x^2 + 9x -6[/tex]
Add both the polynomials
To add both the polynomials we combine like terms
[tex]3x^2-5x+1 +2x^2 + 9x -6[/tex]
3x^2 and 2x^2 are like terms . it becomes 5x^2
-5x and 9x are like terms . it becomes 4x
[tex]3x^2-5x+1 +2x^2 + 9x -6[/tex]
[tex]5x^2+4x-5/tex]
