Question

X2-x-2 делим на Х-3 и получаем =0 как это сделать?

Answer 1

(х^2 - x - 2)/ (x -3) = 0
x^2 - x - 2 = 0
D = 1 - 4*(-2) = 1 + 8 = 9;  √9 = 3
x1 = (1 + 3)/2 = 2
x2 = (1 - 3)/ 2 = - 1

Answer 2

Solving the Equation X^2 - X - 2 ÷ (X - 3) = 0

To solve the equation X^2 - X - 2 ÷ (X - 3) = 0, we can follow these steps:

1. Factorize the Quadratic Equation: - First, factorize the quadratic equation X^2 - X - 2 to simplify the expression.

2. Perform Division: - Then, perform the division of the factorized quadratic equation by (X - 3) to obtain the result.

3. Set the Result Equal to Zero: - Finally, set the result of the division equal to zero and solve for X.

Let's proceed with the first step.

Factorizing the Quadratic Equation

The given quadratic equation is X^2 - X - 2. We can factorize this equation to simplify the expression.

The factorization of X^2 - X - 2 is (X - 2)(X + 1).

Performing Division

Now, we will perform the division of (X - 2)(X + 1) by (X - 3).

Setting the Result Equal to Zero

After performing the division, we will set the result equal to zero and solve for X to find the solution to the given equation.
