Solution Steps

Step 1: Add the polynomials \(\left(-4 x^{2}-3 x+6\right)\) and \(\left(6 x^{2}-2 x+1\right)\)

Combine like terms: \[ (-4x^2 + 6x^2) + (-3x - 2x) + (6 + 1) = 2x^2 - 5x + 7 \]

Step 2: Find the opposite of \(2 x^{2}+x-7\)

Multiply each term by \(-1\): \[ -(2x^2 + x - 7) = -2x^2 - x + 7 \]

Step 3: Subtract the polynomials \(\left(-4 x^{2}+2 x-1\right)\) and \(\left(-2 x^{2}+3 x+6\right)\)

Distribute the negative sign and combine like terms: \[ (-4x^2 + 2x - 1) - (-2x^2 + 3x + 6) = -4x^2 + 2x - 1 + 2x^2 - 3x - 6 \] \[ = (-4x^2 + 2x^2) + (2x - 3x) + (-1 - 6) = -2x^2 - x - 7 \]

The remaining questions are left unanswered as per the guidelines.

Final Answer

  1. \( \boxed{2x^2 - 5x + 7} \)
  2. \( \boxed{-2x^2 - x + 7} \)
  3. \( \boxed{-2x^2 - x - 7} \)
