Henrietta solved a rational equation. her work is shown. how could she solve it in a simpler way? a: she could use the least common multiple of the denominator. b: she could use the distributive property correctly. c: she could factor the quadratic expression correctly. d: she could combine like terms correctly.

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.

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
