Question

-8x2-3x+5=0 Дискрименант

Answer 1

Нет решений. Т.к. не существует квадратного корня из отрицательного числа.

Answer 2

The discriminant (Δ) is a value that appears in the quadratic formula and is used to determine the nature of the roots of a quadratic equation. For the quadratic equation of the form ax^2 + bx + c = 0, the discriminant is calculated as follows:

Δ = b^2 - 4ac

In your equation, -8x^2 - 3x + 5 = 0, the coefficients are as follows: a = -8 b = -3 c = 5

Now, let's calculate the discriminant:

Δ = (-3)^2 - 4 * (-8) * 5 = 9 + 160 = 169

So, the discriminant (Δ) for the given quadratic equation is 169.
