Question

write a sentence explaining why all solutions of rational equation must be checked

Answer 1

Answer:

It is highly important for all solutions of rational equation to be checked to make sure you get the right answer.

Answer 2

In solving a rational equation, we always clear of fractions. When we clear of fractions we always multiply both sides by a variable quantity. When we multiply both sides of an equation by a variable expression, we may introduce an extraneous solution a zero of that expression we multiplied through by.
