Question

X^2+x=0 Дискриминант

Answer 1

х² + х = 0

D = b²- 4ac = 1² - 4 · 1 · 0 = 1 - 0 = 1

х₁ = (-1 -√1)/(2·1) = (-1-1)/2 = (-2)/2 = - 1

х₂ = (-1 +√1)/(2·1) = (-1+1)/2 = 0/2 = 0

Ответ: (-1 и 0).

Answer 2

To find the discriminant of the quadratic equation x^2 + x = 0, we first need to identify the coefficients a, b, and c in the general form of a quadratic equation: ax^2 + bx + c = 0.

In this case, a = 1, b = 1, and c = 0.

The discriminant (Δ) of a quadratic equation is given by the formula: Δ = b^2 - 4ac.

Let's substitute the values: Δ = (1)^2 - 4 * 1 * 0 Δ = 1 - 0 Δ = 1

So, the discriminant of the equation x^2 + x = 0 is 1.
