Answer:
(D)
Step-by-step explanation:
The given equation is:
Cubing on both the sides, we get
therefore, the solutions are:
and
Substitute x=6 in the given equation, we have
which is true, thus x=6 is a true solution.
Put x=-2 in the given equation, we have
which is true, thus x=-2 is a true solution.
Therefore, Both x = –2 and x = 6 are true solutions.
