The inequality is .
Solve the inequality.
\Step 1:
\Since the radicand of a square root must be greaterthan or equal to zero, first solve and
to identity the values of
for which the left side of the inequality is define.
Case(i):
\ (First radicand greater than or equals to zero)
(Subtract
from each side)
(Apply additive inverse property:
)
Case(ii):
\ (Second radicand greater than or equals to zero)
Step 2:
\ (Original inequality)
(Add
to each side)
(Apply additive inverse property:
)
(Take square each side)
(Cancel square and root terms)
(Cancel common terms)
(Subtract
from each side)
(Apply additive inverse property:
)
(Take square each side)
(Cancel square and root terms)
(Multiply)
(Divide each side by
)
(Cancel common terms)
Step 3:
\It appears that ,
and
.
Check:
\Use three test values and make a table:
\![]() | \
![]() | \
![]() | \
![]() | \
![]() | \
![]() | \
Since ![]() | \
\
Since satisfied. \ | \
Since ![]() | \
Thus, only values in the interval satisfy the inequality.
