Extraneous solutions appear to be valid solutions, but when checked back into the original equation they give a false result. You must exclude extraneous solutions from your answer.

No solution means there is no value that can make the statement true. Ex. parallel lines have no solution because they never intersect.

No real solution implies that there could possibly be imaginary solutions.
