Full solution

Q. Multiply. Write your answer in simplest form. \newline2(9+2)\sqrt{2}(-9 + \sqrt{2})
  1. Distribute 2\sqrt{2}: Distribute 2\sqrt{2} to both terms inside the parentheses.2(9+2)\sqrt{2}(-9 + \sqrt{2}) = 2×(9)+2×2\sqrt{2} \times (-9) + \sqrt{2} \times \sqrt{2}
  2. Multiply by 9-9: Multiply the square root of 22 by 9-9.2×(9)=9×2\sqrt{2} \times (-9) = -9 \times \sqrt{2}
  3. Square root of 22: Multiply the square root of 22 by itself.\newline2×2=2\sqrt{2} \times \sqrt{2} = 2\newlineThis is because the square root of a number multiplied by itself gives the original number.
  4. Combine results: Combine the results from Step 22 and Step 33.\newline9×2+2-9 \times \sqrt{2} + 2\newlineThis is the simplest form of the expression.
