Answer:
Simplify square root of x^2-9
√
x
2
−
9
Rewrite
9
as
3
2
.
√
x
2
−
3
2
Since both terms are perfect squares, factor using the difference of squares formula,
a
2
−
b
2
=
(
a
+
b
)
(
a
−
b
)
where
a
=
x
and
b
=
3
.
√
(
x
+
3
)
(
x
−
3
)
(6 + 1/4)·4 = (6·4) + (1/4·4) = 24 + 1 = 25
Or, you can convert the mixed number to the improper fraction 25/4 and then multiply by 4 to get 25.
