Question

A) 3x²-3y²; Б)16x²+40x+25: B) a-8; Г)26³ +54.Помогите пожалуйста ​

Answer 1

Ответ:A)3x² - 3y² = 3(x² - y²) = 3(x + y)(x - y)

Б)16x² + 40x + 25 = (4x + 5)²
В)a - 8 - это линейное выражение, которое уже находится в упрощенном виде и не может быть дополнительно упрощено. Если у вас есть дополнительные инструкции или уточнения, пожалуйста, сообщите мне, и я помогу вам решить математическую задачу.
Г)26³ + 54 = 17576 + 54 = 17630

Answer 2

A) To simplify the expression 3x² - 3y², we can factor out a common factor of 3 from both terms. This gives us:

3(x² - y²)

Next, we can use the difference of squares formula, which states that a² - b² can be factored as (a + b)(a - b). In this case, a is x and b is y. So, we can rewrite the expression as:

3(x + y)(x - y)

Therefore, the simplified form of 3x² - 3y² is 3(x + y)(x - y).

B) To simplify the expression 16x² + 40x + 25, we can try factoring it. However, this expression cannot be factored further using integers. So, the simplified form of 16x² + 40x + 25 is 16x² + 40x + 25.

C) The expression a - 8 cannot be simplified further since there are no like terms to combine. Therefore, the simplified form of a - 8 is a - 8.

D) To calculate 26³ + 54, we can use the exponentiation operator. The expression 26³ means 26 raised to the power of 3, which is equal to 26 * 26 * 26. So, we can calculate it as follows:

26³ + 54 = 26 * 26 * 26 + 54 = 17,576 + 54 = 17,630

Therefore, the value of 26³ + 54 is 17,630.

I hope this helps! Let me know if you have any further questions.
