Question

X^2 - 3(корень из x)^2 - 4 = 0 Чему равна сумма корней квадратного уравнения??????

Answer 1

$x^2-3(\sqrt{x})^2-4=0\\x^2-3x-4=0\\x_1+x_2=3$

Answer 2

Quadratic Equation

The given equation is x^2 - 3(sqrt(x))^2 - 4 = 0. We need to find the sum of the roots of this quadratic equation.

To find the sum of the roots, we can use the formula for the sum of the roots of a quadratic equation. For a quadratic equation in the form ax^2 + bx + c = 0, the sum of the roots is given by -b/a.

In this case, the equation is x^2 - 3(sqrt(x))^2 - 4 = 0. Comparing it with the standard form ax^2 + bx + c = 0, we can see that a = 1, b = 0, and c = -4.

Using the formula, the sum of the roots is -b/a = 0/1 = 0.

Therefore, the sum of the roots of the given quadratic equation is 0.
