Q. Subtract. Write your answer in simplest form.\newline−92−72-9\sqrt{2} - 7\sqrt{2}
  1. Identify coefficients: −92−72-9 \sqrt{2} - 7 \sqrt{2}\newlineIdentify the expression that combines the coefficients.\newline−92−72=(−9−7)2-9 \sqrt{2} - 7 \sqrt{2} = (-9 - 7) \sqrt{2}
  2. Combine coefficients: Simplify: (−9−7)2(-9 - 7) \sqrt{2}(−9−7)2(-9 - 7) \sqrt{2} = −162-16 \sqrt{2}
