Add the polynomial expressions 2r2−3r+4 and −2r2+3r+6. (1 point)

1 answer

When adding the polynomial expressions 2r^2 - 3r + 4 and -2r^2 + 3r + 6, we combine like terms.

The coefficients of the terms with the same exponent are added together.

The sum of 2r^2 - 2r^2 is 0.

The sum of -3r + 3r is 0.

The sum of 4 + 6 is 10.

Therefore, the sum of the polynomial expressions 2r^2 - 3r + 4 and -2r^2 + 3r + 6 is 0r^2 + 0r + 10, which simplifies to 10.
