Правильный вариант б - 5

Answer 2

To find the value of the expression x^2 - 4x + 1, we can substitute x with the values provided in the options and see which one gives the correct result.

Let's evaluate the expression for each option: A) x^2 - 4x + 1 = (-3)^2 - 4(-3) + 1 = 9 + 12 + 1 = 22 Б) x^2 - 4x + 1 = (-5)^2 - 4(-5) + 1 = 25 + 20 + 1 = 46 В) x^2 - 4x + 1 = (13)^2 - 4(13) + 1 = 169 - 52 + 1 = 118 Г) x^2 - 4x + 1 = (11)^2 - 4(11) + 1 = 121 - 44 + 1 = 78

None of the provided options match the result of x^2 - 4x + 1. Please double-check the given options or the expression.
