Question

X^2+x-1 аоаааоаоаоаоаоааооао

Answer 1

Ответ:

По дискриминанту:

$d = b^{2} - 4 \times a \times c$

Если D<0, то уравнение не имеет решений.

Здесь D=1²-4×1×1=-3, что меньше 0.

Значит уравнение не имеет решений.

Answer 2

The expression you provided, X^2 + x - 1, appears to be a quadratic polynomial. It is written in the form of a quadratic equation, where the variable is denoted by "X" (presumably x) and the coefficients are 1, 1, and -1 for the squared term, linear term, and constant term, respectively.

This polynomial represents a parabolic curve when graphed on a Cartesian plane. The graph will be a U-shaped curve, opening upwards, due to the positive coefficient of the squared term.

If you have any specific questions or if there is something specific you would like to know about this polynomial, please let me know!
