Answer:4y⁴ - 2y³ + 2y² - 2y + 2
Step-by-step explanation:
Like terms adds up !
In other words the terms having same power adds up like normal addition or subtraction.
The value of coefficient changes accordingly
Like 4y⁴ doesn't have a same power in the second equation thus it remains as it is.
Next we see -y³ and 3y³ has same power so they add up (-1+3=2)
2y² has no like term
-3y and +y adds up to -2y
6-4 is a normal subtraction
Thus the answer is-
4y⁴ - 2y³ + 2y² - 2y + 2
