Q. Subtract. Write your answer in simplest form.\newline−92−82-9\sqrt{2} - 8\sqrt{2}
  1. Identify coefficients combination: Identify the expression that combines the coefficients.\newline−92−82=(−9−8)2-9 \sqrt{2} - 8 \sqrt{2} = (-9 - 8) \sqrt{2}
  2. Simplify expression: Simplify: (−9−8)2(-9 - 8) \sqrt{2}\newline(−9−8)2=−172(-9 - 8) \sqrt{2} = -17 \sqrt{2}
