It seems like you've posted an equation, but it appears to contain a duplication or formatting issue. Let's simplify and solve the equation step by step, assuming the intended equation is:

\[ X(X + 2) - X - 2 = 0. \]

First, expand the expression:

1. Expand the term \( X(X + 2) \):
\[
X^2 + 2X.
\]

2. Substitute the expansion back into the equation:
\[
X^2 + 2X - X - 2 = 0.
\]

3. Simplify the expression by combining like terms:
\[
X^2 + X - 2 = 0.
\]

Now, solve the quadratic equation \( X^2 + X - 2 = 0 \).

To factor this, look for two numbers that multiply to \(-2\) (the constant term) and add up to \(1\) (the coefficient of \(X\)).

The numbers \(2\) and \(-1\) work because:
- \(2 \times (-1) = -2\)
- \(2 + (-1) = 1\)

So, the factored form of the equation is:
\[
(X + 2)(X - 1) = 0.
\]

To find the solutions, set each factor equal to zero:

1. \(X + 2 = 0 \Rightarrow X = -2\).

2. \(X - 1 = 0 \Rightarrow X = 1\).

Thus, the solutions to the equation are \(X = -2\) and \(X = 1\).
