Answer 1

Simplifying the Expression

To simplify the given expression (2x - 10x + 4) - (3x^2 + 5x - 6) + 2, we can start by combining like terms and then performing the necessary operations.

Combining Like Terms

First, let's combine like terms within each set of parentheses: - For the first set of parentheses: (2x - 10x + 4), we can combine the x terms: (2x - 10x = -8x). - For the second set of parentheses: (3x^2 + 5x - 6), there are no like terms to combine.

Performing the Subtraction

Now, let's perform the subtraction by distributing the negative sign: - (2x - 10x + 4) - (3x^2 + 5x - 6) + 2 becomes -8x + 4 - 3x^2 - 5x + 6 + 2.

Combining Like Terms Again

Next, we can combine like terms in the entire expression: - Combine the x terms: (-8x - 5x = -13x). - Combine the constant terms: (4 + 6 + 2 = 12).

Final Simplified Expression

After combining like terms, the simplified expression is: -3x^2 - 13x + 12.

This is the simplified form of the given expression (2x - 10x + 4) - (3x^2 + 5x - 6) + 2.
