Hi there!
The question here is -8g² + (2g² - 4h), and we are asked to find the sum of it. First, we can remove the parentheses by distributing the 'invisible' 1 next to the addition sign. This gives us -8g² + 2g² - 4h. Next, we can simplify the expression by finding like terms, which would be -8g² and 2g², as they both have the same variable to the same exponent. Therefore, our answer would be -6g² - 4h. Hope this helped and have a phenomenal day!
