In Exercises 83–90, perform the indicated operations. Simplify the result, if possible. (2−6/(x+1))(1 + 3/(x−2))

검증된 단계별 안내

Distribute the terms in the expression (2 - 6/(x+1))(1 + 3/(x-2)) using the distributive property: multiply each term in the first parenthesis by each term in the second parenthesis.

The first multiplication is 2 * 1, which simplifies to 2.

The second multiplication is 2 * (3/(x-2)), which simplifies to 6/(x-2).

The third multiplication is (-6/(x+1)) * 1, which simplifies to -6/(x+1).

The fourth multiplication is (-6/(x+1)) * (3/(x-2)), which simplifies to -18/((x+1)(x-2)). Combine all these terms into a single expression and simplify further if possible.
