✔ x = 1 and x = 8; x = 1 and x = 8; x = 0

Question 7

Question 8

Revolt · Accepted Answer

No. The student is not correct. Although clearing the denominators gives the possible solution a = -2, it is invalid in the original equation because it makes two denominators equal to zero. Thus, a = -2 is extraneous, and the original equation has no solution.
