Q. Subtract. Write your answer in simplest form.\newline−72−52-7\sqrt{2} - 5\sqrt{2}
  1. Identify coefficients: −72−(−52)-7 \sqrt{2} - (-5 \sqrt{2})\newlineIdentify the expression that combines the coefficients.\newline−72−(−52)=(−7+5)2-7 \sqrt{2} - (-5 \sqrt{2}) = (-7 + 5) \sqrt{2}
  2. Combine coefficients: Simplify: (−7+5)2(-7 + 5) \sqrt{2}(−7+5)2(-7 + 5) \sqrt{2} = −22-2 \sqrt{2}
