Question

X^2-2x+2=0 Пожалуйста срочно надо!!!

Answer 1

D = 2^2 - 4*1*2 = 4 - 8 = -4 
У данного уравнения нет решений, так как у него дискриминант меньше нуля!

Answer 2

Solving the Quadratic Equation

To solve the quadratic equation x^2 - 2x + 2 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

Applying the Quadratic Formula

Using the coefficients from the given equation x^2 - 2x + 2 = 0: - a = 1 - b = -2 - c = 2

We can substitute these values into the quadratic formula to find the solutions for x.

Calculation

x = (-(-2) ± √((-2)^2 - 4*1*2)) / (2*1)

x = (2 ± √(4 - 8)) / 2

x = (2 ± √(-4)) / 2

Complex Solutions

The discriminant (the value inside the square root) is negative, which means the solutions will be complex numbers.

x = (2 ± 2i) / 2

So, the solutions for the equation x^2 - 2x + 2 = 0 are: - x = 1 + i - x = 1 - i
