If by solving a rational equation you obtain a number that makes an expression in the equation undefined, then what will you do?

• Accept even if it is untrue value.

• Do not reject since it will satisfy the equation in a long run.

• The number is not a real solution then discard it.

• Continue the solution even if it will give undefined answer.
