Q. Subtract. Write your answer in simplest form.\newline−55−25-5\sqrt{5} - 2\sqrt{5}
  1. Identify coefficients expression: Identify the expression that combines the coefficients.\newline−55−25=(−5−2)5-5 \sqrt{5} - 2 \sqrt{5} = (-5 - 2) \sqrt{5}
  2. Simplify expression: Simplify: (−5−2)5(-5 - 2) \sqrt{5}\newline(−5−2)5=−75(-5 - 2) \sqrt{5} = -7 \sqrt{5}
