Q. Subtract. Write your answer in simplest form.\newline−72−22-7\sqrt{2} - 2\sqrt{2}
  1. Identify coefficients: −72−22-7 \sqrt{2} - 2 \sqrt{2}\newlineIdentify the expression that combines the coefficients.\newline−72−22=(−7−2)2-7 \sqrt{2} - 2 \sqrt{2} = (-7 - 2) \sqrt{2}
  2. Combine coefficients: Simplify: (−7−2)2(-7 - 2) \sqrt{2}(−7−2)2(-7 - 2) \sqrt{2} = −92-9 \sqrt{2}
