The radicand of a square root must be greater than or equal t zero,
\The first solve
.............(1)
Now solve
(Add 4 to each side)
(Simplify)
(Squaring on each side and eliminate square roots)
(Simplify)
(Subtract 3 from each side)
(Simplify)
(Divide each side by 2)
............(2) (Simplify)
From (1) and (2)
\Some x-values to confirm the solution.
\ \
x = | \
\
x = 36 \ | \
\
x = 83 \ | \
\
f( =
