What are the three formulas for shortened multiplication provided in the document?
Ответ:
Краткое пояснение: Формулы сокращенного умножения представляют собой алгебраические тождества, позволяющие упростить раскрытие скобок и возведение в степень.
Ответ:
- \((a+b)^2 = a^2 + 2ab + b^2\)
- \((a-b)^2 = a^2 - 2ab + b^2\)
- \(a^2 - b^2 = (a+b)(a-b)\)
