Full solution

Q. Multiply. Write your answer in simplest form.\newline2(42)-\sqrt{2}(4 - \sqrt{2})
  1. Distribute 2-\sqrt{2}: Distribute 2-\sqrt{2} to both terms inside the parentheses.-\sqrt{\(2\)}(\(4 - \sqrt{22}) = -\sqrt{22}\cdot 44 - \sqrt{22}\cdot(-\sqrt{22})
  2. Multiply 2-\sqrt{2} by 44: Multiply 2-\sqrt{2} by 44.\newline2×4=42-\sqrt{2} \times 4 = -4\sqrt{2}
  3. Multiply 2-\sqrt{2} by 2-\sqrt{2}: Multiply 2-\sqrt{2} by 2-\sqrt{2}.\newline2×(2)=2×2=2-\sqrt{2} \times (-\sqrt{2}) = \sqrt{2} \times \sqrt{2} = 2
  4. Combine results: Combine the results from Step 22 and Step 33.\newline42+2-4\sqrt{2} + 2
