Full solution

Q. Multiply. Write your answer in simplest form. \newline2(45)\sqrt{2}(-4 - \sqrt{5})
  1. Distribute 2\sqrt{2}: Distribute 2\sqrt{2} to both terms inside the parentheses.2(45)=2×(4)+2×(5)\sqrt{2}(-4 - \sqrt{5}) = \sqrt{2} \times (-4) + \sqrt{2} \times (-\sqrt{5})
  2. Multiply 2\sqrt{2} by 4-4: Multiply 2\sqrt{2} by 4-4.\newline2×(4)=4×2\sqrt{2} \times (-4) = -4 \times \sqrt{2}
  3. Multiply 2\sqrt{2} by 5-\sqrt{5}: Multiply 2\sqrt{2} by 5-\sqrt{5}.2×(5)=2×5=10\sqrt{2} \times (-\sqrt{5}) = -\sqrt{2 \times 5} = -\sqrt{10}
  4. Combine results: Combine the results from Step 22 and Step 33.\newline4×210-4 \times \sqrt{2} - \sqrt{10}
