Question

4x^2 + 16 = 0

Answer 1

4x^2 + 16 = 0
4x^2=-16
x^2=-16/4
x^2=-4 а корень из отрицательного никак не извлекается =_=

Answer 2

To solve the quadratic equation 4x^2 + 16 = 0, we can start by subtracting 16 from both sides of the equation:

4x^2 = -16

Next, we can divide both sides of the equation by 4 to isolate x^2:

x^2 = -16/4

Simplifying further, we have:

x^2 = -4

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

√(x^2) = ±√(-4)

x = ±√(-4)

Since the square root of a negative number is not a real number, the equation 4x^2 + 16 = 0 has no real solutions. It represents an equation with complex solutions.
