Answer:

3x²+6x+4

Step-by-step explanation:

Given:

(6x+7+x²) + (2x²-3)

Aim:

To add the polynomials

Solution:

Removing brackets first:

  • 6x+7+x²+2x² - 3

Collecting like terms to each other,

  • 6x+7-3+2x²+x²

Simplifying,

  • 6x+4+3x²

Rewriting it as,

  • 3x²+6x+4

Second choice is accurate.
