Answer:
x
2
−
25
Explanation:
This is an example of DOTS: the Difference Of Two Squares.
When we have two brackets where one is pos and one is neg with the same number, we can use this method:
DOTS allows us to cancel any x values, like so:
(
x
−
5
)
(
x
+
5
)
=
x
2
+
5
x
−
5
x
−
25
You can see here that due to the signs and the numbers being the same, the
+
5
x
−
5
x
cancel each other out to equal
0
.
=
x
2
−
25
