Answer:
see below
Step-by-step explanation:
8x and 56 are not like terms
x is a variable and 56 is a constant
8x can be added to 56 but they cannot be combined together into one term
8x+56 cannot be combined because they are not like terms
Answer:
1. y = (3x^2 - 4)
2. y = (-x^2) + 2
3. y = (-x^2 - 8)
4. y = (3x^2 - 2) + 4
5. y = (3x^2 + 4)
6. y = (-1/4x^2)
