Solving rational
equations
|
To solve an equation with rational
expressions (fractions), determine the lowest common denominator
(LCD) of all rational expressions in the equation and multiply
each term of both sides of the equation by the common denominator
to eliminate fractions.
|
Then, solve the equation that remains. Note, check for extraneous
solutions.
|
The extraneous solutions are values
that cause any denominator in the equation to be 0. So, these
values have to be excluded from the solution.
