Question

(6a-7)во второй степени-(6a+7)во второй степени

Answer 1

Ответ:

Объяснение:

(6a-7)²-(6a+7)²
Раскладываем так:
a²-b² = (a+b)*(a-b)
Получим:
((6a-7)+(6a+7))*((6a-7)-(6a+7)) =
12a*(-14) = -168a

Answer 2

(6a-7)^2-(6a+7)^2

-14•12а=-168а

Answer 3

Calculating the Expression (6a-7)^2-(6a+7)^2

To calculate the expression (6a-7)^2-(6a+7)^2, we can use the formula for the difference of squares, which states that a^2 - b^2 = (a + b)(a - b). In this case, a = (6a - 7) and b = (6a + 7). Therefore, the expression can be simplified as follows:

(6a-7)^2 - (6a+7)^2 = [(6a-7) + (6a+7)][(6a-7) - (6a+7)]

Now, let's simplify the expression further.

Simplifying the Expression

First, let's simplify the terms inside the brackets:

1. (6a-7) + (6a+7) = 12a 2. (6a-7) - (6a+7) = -14

Now, we can substitute these values back into the expression:

(6a-7)^2 - (6a+7)^2 = 12a * (-14)

Final Answer

Therefore, the expression (6a-7)^2 - (6a+7)^2 simplifies to -168a.
