Answer 2

To simplify the expression -14ab^3c^2 - 21a^2bc^2 - 28a^3b^2c, you can factor out the common terms from each term and then combine like terms. The common factor in this case is abc^2. Here's the step-by-step simplification:

Step 1: Factor out the common term abc^2 from each term: -14ab^3c^2 - 21a^2bc^2 - 28a^3b^2c = abc^2(-14b^2 - 21ab - 28a^2b)

Step 2: Combine like terms: Now, we can look for like terms within the parentheses. There are no more common factors to factor out, but we can simplify the expression within the parentheses: abc^2(-14b^2 - 21ab - 28a^2b) = abc^2(-7b^2 - 3ab - 4a^2b)

That's the simplified form of the expression -14ab^3c^2 - 21a^2bc^2 - 28a^3b^2c.
