Full solution

Q. Multiply. Write your answer in simplest form.\newline5(7+5)-\sqrt{5}(-7 + \sqrt{5})
  1. Distribute 5-\sqrt{5}: Distribute 5-\sqrt{5} to both terms inside the parentheses.5(7+5)=5×(7)+(5)×5-\sqrt{5}(-7 + \sqrt{5}) = -\sqrt{5} \times (-7) + (-\sqrt{5}) \times \sqrt{5}
  2. Multiply 5-\sqrt{5} by 7-7: Multiply 5-\sqrt{5} by 7-7.5×(7)=75-\sqrt{5} \times (-7) = 7\sqrt{5}
  3. Multiply 5-\sqrt{5} by 5\sqrt{5}: Multiply 5-\sqrt{5} by 5\sqrt{5}.
    (5)×5=(5)2(-\sqrt{5}) \times \sqrt{5} = -(\sqrt{5})^2
    Since the square root and the square cancel each other out, we have:
    (5)2=5-(\sqrt{5})^2 = -5
  4. Combine results: Combine the results from Step 22 and Step 33. 7557\sqrt{5} - 5 This is the simplest form of the expression.
