Question

X ² - 3x +1 при x=-1,3

Answer 1

-1,3-3*(-1,3)+1=-1,3+3,9+1=3,6

Answer 2

To find the value of the expression $x^2 - 3x + 1$ when $x = -1$ and $x = 3$, we can substitute the given values into the expression and evaluate it.

When $x = -1$:

$(-1)^2 - 3(-1) + 1 = 1 + 3 + 1 = 5$

When $x = 3$:

$(3)^2 - 3(3) + 1 = 9 - 9 + 1 = 1$

Therefore, when $x = -1$, the expression $x^2 - 3x + 1$ evaluates to 5, and when $x = 3$, the expression evaluates to 1.
