Final answer:
The given expression represents a simplified form of the given expression.
Step-by-step explanation:
The given expression is:
gx²-3hx²-6fy²-gy²+6fx²+3hy²
To simplify this expression, we can group like terms and combine them.
Combining the terms with similar variables we have:
gx² - 3hx² + 6fx² - 6fy² - gy² + 3hy²
Let's rearrange the terms in ascending order:
gx² - 3hx² + 6fx² - gy² - 6fy² + 3hy²
So, the simplified form of the expression is:
gx² - 3hx² + 6fx² - gy² - 6fy² + 3hy²
