  RECALL: (1) $(a+b)(a-b) = a^2-b^2$ (2) For $a\gt0$, $(\sqrt{a})^2 = a$ Use rule (1) above by to obtain: $=2^2 - (\sqrt{3})^2 \\=4-(\sqrt3)^2$ Use rule (2) above to obtain: $\\=4-3 \\=\color{blue}{1}$
explanation: The document is a solution to a precalculus problem. It demonstrates the simplification of an expression using algebraic identities and properties of square roots. The document contains a question and its corresponding answer.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
