Determine Kelsey's error and correct it:

4x²+ 5x² = 9x⁴

Kelsey incorrectly added the exponents. The correction should be:

4x²+ 5x² = 9x²

Determine Jose's error and correct it:

4x - (3x -2) = 4x - 3x -2 = x-2

Jose forgot to distribute the negative to the -2. It should be:

4x - (3x -2) = 4x - 3x +2 = x +2
