Answer:

To solve the first expression, we can simplify it as follows:

g² 2 – 3 + (-2 g² 2 + 4)

= -g² 2 + 1

Therefore, g² 2 – 3 increased by – 2 g² 2 + 4 equals -g² 2 + 1.

To find the sum of 2 ℎ² -- h and ℎ² + 2h + 3, we can simply add them together:

(2 ℎ² -- h) + (ℎ² + 2h + 3)

= 3 ℎ² + h + 3

Therefore, the sum of 2 ℎ² -- h and ℎ² + 2h + 3 is 3 ℎ² + h + 3.
