Question

3x²-x+2 при x= -1,1 ​

Answer 1

Ответ:6,73

Объяснение:3*(-1,1)^2+1,1+2=6,73

Answer 2

$3 \times ( - 1.1) ^{2} - 1 + 2 = 3 \times ( \frac{11}{10} )^{2} - 1 + 2 = 3 \times \frac{121}{100} - 1 + 2 = \frac{363}{100} - 1 + 2 = \frac{463}{100} = 4.63$

Answer 3

To evaluate the expression 3x² - x + 2 at x = -1 and x = 1, we substitute the values of x into the expression and perform the calculations.

When x = -1: 3(-1)² - (-1) + 2 = 3(1) + 1 + 2 = 3 + 1 + 2 = 6

When x = 1: 3(1)² - (1) + 2 = 3(1) - 1 + 2 = 3 - 1 + 2 = 4

Therefore, when x = -1, the expression evaluates to 6, and when x = 1, the expression evaluates to 4.
