Answer:
Note that:
(
m
+
4
)
2
=
m
2
+
2
(
m
)
(
4
)
+
4
2
=
m
2
+
8
m
+
16
So add
1
ti both sides of the equation to get:
m
2
+
8
m
+
16
=
1
which we can write as:
(
m
+
4
)
2
=
1
Then take the square root of both sides, allowing for both positive and negative square roots to find:
m
+
4
=
±
√
1
=
±
1
Subtract
4
from both sides to get:
m
=
−
4
±
1
That is
m
=
−
5
or
m
=
−
3
Alternative method
Use the difference of squares identity:
a
2
−
b
2
=
(
a
−
b
)
(
a
+
b
)
with
a
=
(
m
+
4
)
and
b
=
1
as follows:
0
=
m
2
+
8
m
+
15
=
(
m
+
4
)
2
−
16
+
15
=
(
m
+
4
)
2
−
1
=
(
m
+
4
)
2
−
1
2
=
(
(
m
+
4
)
−
1
)
(
(
m
+
4
)
+
1
)
=
(
m
+
3
)
(
m
+
5
)
So
m
=
−
3
or
m
=
−
5
