Explain the steps involved in adding two rational
expressions.
DONE

Answer 1

Step-by-step explanation: example

5/(X+2). + 2/(X+1)

Common denominator. Is both (X+2)(X+1)

So the first fraction needs (X+1) since it already has (X+2) the second fraction needs ( X+2)

5(X+1). / (X+2)((X+1) +. 2/(X+2)/(X+1)

So multiply 5 with X then 5 with 1 and 2 times X and 2 times 2

5x+5 + 2x+4 / (X+2)((X+1)

Answer 7x+9/ (X+2)(X+1)

Answer 2

1. If the denominators are the same, simply add the numerators and place the answer over the common denominator. Reduce the final answer if necessary.

2. if the denominators are different, then find the least common denominator and rewrite the rational expressions as equivalent rational expressions with the least common denominator. Then add the numerators and place the answer over the common denominator.. Reduce your final answer if necessary.
