Question

2-3x(x во второй степени), при х= -7

Answer 1

Ответ:

2 - 3*(-7)² = 2 - 147 = -145

Объяснение:

Answer 2

To evaluate the expression 2-3x(x^2) when x = -7, we substitute -7 for x in the expression and perform the calculations:

2 - 3(-7)(-7^2) 2 - 3(-7)(49) 2 - 3(-7)(49) 2 - 3(-343) 2 + 1029 1031

Therefore, when x = -7, the value of the expression 2 - 3x(x^2) is 1031.
