Question

3х^2-4х-7=0 ДИСКРИМИНАНТ​

Answer 1

Ответ:

Дискриминант равен 100.

Корни уравнения -1 и 7/3

Объяснение:

$16 + 84 = 100$

Тогда:

x1=(4+10)/6=7/3

x2=(4-10)/6=-1

Answer 2

To find the discriminant of a quadratic equation in the form of ax^2 + bx + c = 0, you use the formula:

Discriminant (D) = b^2 - 4ac

In your equation, 3x^2 - 4x - 7 = 0, a = 3, b = -4, and c = -7. Now we can calculate the discriminant:

D = (-4)^2 - 4 * 3 * (-7) D = 16 + 84 D = 100

So the discriminant of the quadratic equation is 100.
