Answer 1

To add the polynomial expressions \( 2r^2 - 3r + 4 \) and \( -2r^2 + 3r + 6 \), you combine like terms.

Here are the steps:

1. Write down the expressions: \[ (2r^2 - 3r + 4) + (-2r^2 + 3r + 6) \]

2. Combine the like terms:

   • For \( r^2 \) terms: \( 2r^2 + (-2r^2) = 0r^2 \)
   • For \( r \) terms: \( -3r + 3r = 0r \)
   • For the constant terms: \( 4 + 6 = 10 \)

Putting it all together:

\[ 0r^2 + 0r + 10 = 10 \]

Therefore, the sum of the two polynomial expressions is \( \boxed{10} \).
