Henrietta solved a rational equation by multiplying both sides by 
 .She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
 .She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
 Henrietta can have got rid of denominator and then use the distributive rule .
So the first option 
A:She could use the least common multiple of the denominator is right
