Q. Subtract. Write your answer in simplest form. \newline−2−82-\sqrt{2} - 8\sqrt{2}
  1. Identify Coefficient Combination: Identify the expression that combines the coefficients. −2−82=(−1−8)2-\sqrt{2} - 8\sqrt{2} = (-1 - 8) \sqrt{2}
  2. Simplify Expression: Simplify: (−1−8)2(-1 - 8) \sqrt{2}\newline(−1−8)2=−92(-1 - 8) \sqrt{2} = -9 \sqrt{2}
