Full solution

Q. Multiply. Write your answer in simplest form. \newline2(72)\sqrt{2}(-7 - \sqrt{2})
  1. Distribute 2\sqrt{2}: Distribute 2\sqrt{2} to both terms inside the parentheses.\newline2(72)\sqrt{2}(-7 - \sqrt{2})\newline= 2(7)+2(2)\sqrt{2}\cdot(-7) + \sqrt{2}\cdot(-\sqrt{2})
  2. Multiply 2\sqrt{2} by 7-7: Multiply 2\sqrt{2} by 7-7.\newline2×(7)\sqrt{2} \times (-7)\newline=7×2= -7 \times \sqrt{2}
  3. Multiply 2\sqrt{2} by 2-\sqrt{2}: Multiply 2\sqrt{2} by 2-\sqrt{2}.
    2×(2)\sqrt{2} \times (-\sqrt{2})
    = 2×2-\sqrt{2} \times \sqrt{2}
    = 2×2-\sqrt{2 \times 2}
    = 4-\sqrt{4}
    = 2-2
  4. Combine results: Combine the results from Step 22 and Step 33.\newline7×22-7 \times \sqrt{2} - 2
