Final answer:
To simplify the given expression, combine like terms by combining the x terms and y terms separately. Therefore, the simplified expression is: 4225x⁴ - 130x² + 36y² - 81y⁴ - 3
Step-by-step explanation:
The given expression is:
4225x⁴ - 130x² - 3 + 36y² - 81y⁴
To simplify this expression, we can combine like terms. Like terms have the same variables raised to the same power.
In this case, we have x terms and y terms.
Let's combine the x terms first:
4225x⁴ - 130x² - 3
Next, let's combine the y terms:
36y² - 81y⁴
So the simplified expression is:
4225x⁴ - 130x² + 36y² - 81y⁴ - 3
