Tìm x

To solve this quadratic equation, we can first expand and simplify it:

x - 2m - 2x + m² + 2 = 0
-m - x + m² + 2 = 0

Now, we can rearrange the terms and set the equation equal to zero:

m² - m - x - 2 = 0

This is a quadratic equation in terms of m. To solve for m, we can use the quadratic formula:

m = [-(-1) ± √((-1)² - 4(1)(-x-2))] / 2(1)
m = [1 ± √(1 + 4x + 8)] / 2
m = [1 ± √(4x + 9)] / 2

Therefore, the solutions for m are:

m = (1 + √(4x + 9)) / 2
m = (1 - √(4x + 9)) / 2
