Answer:Since both terms are perfect squares, factor using the difference of squares formula,
a
2
−
b
2
=
(
a
+
b
)
(
a
−
b
)
a
2
-
b
2
=
(
a
+
b
)
(
a
-
b
)
where
a
=
2
x
a
=

Step-by-step explanation:
1. 5x= -80. x= -16
2. x - 73 = 129. x = 202
3. x/-8 = 22. x = -176
4. 2x + 8 = 8. 2x = 0. x = 0
5. 3x - 7 = 40. 3x = 47. x = 47/3
Answer:
0 is your answer
