Question

-4 x во 2 степени - 36 x во 2 степени - 80 = 0

Answer 1

Ответ:

Объяснение:

4x²-36x²-80=0

-32x²-80=0

32x²=-80 // : 32

x²=-80/32

нет отрицательного числа, которое дает квадраты -80/32

Answer 2

To solve the quadratic equation -4x^2 - 36x^2 - 80 = 0, we can first combine like terms:

-4x^2 - 36x^2 - 80 = 0 -40x^2 - 80 = 0

Next, we can divide the entire equation by -40 to simplify it further:

(-40x^2 - 80) / -40 = 0 / -40 x^2 + 2 = 0

Now, we can isolate x^2 by subtracting 2 from both sides:

x^2 = -2

To solve for x, we take the square root of both sides:

√(x^2) = ±√(-2)

Since we have a negative value under the square root, the equation has no real solutions. The solutions are complex numbers.
