Answer 2

1) Simplify the expression: (1) + (6x^2 - 7x + 4) - (4x^2 - 4x + 18)

To simplify this expression, you need to combine like terms. Let's break it down step by step:

Step 1: Remove the parentheses: 1 + 6x^2 - 7x + 4 - 4x^2 + 4x - 18

Step 2: Combine like terms: (1 - 18) + (6x^2 - 4x^2) + (-7x + 4x) + 4

Simplifying further: -17 + 2x^2 - 3x + 4

So, the simplified expression is
