Answer:
This is the answer
the last term is a perfect square:
25
=
5
2
If we double the product f the things we squared, we get:
2
⋅
(
2
x
)
(
5
)
=
20
x
, which is the absolute value of the middle term.
(
a
x
−
b
)
2
=
a
2
x
2
−
2
a
b
x
+
b
2
, so we can factor:
4
x
2
−
20
x
+
25
=
(
2
x
−
5
)
2
With practice, there is no need to write the stuff up to this point, we can write:
4
x
2
−
20
x
+
25
=
0
(
2
x
−
5
)
2
=
0
2
x
−
5
=
0
x
=
5
