This time, a survey with 100 adults obtained at random is being tested. and it has a result, finding significant changes with respect to the first event, however we must conclude that the sample size is too small to detect a statistically significant increase, due to the value of people surveyed, to have a more impactful result there should be more people surveyed
The result is
9
a
2
−
16
The reason is the following:
The problem is an example of a notable product: "the sum multiplied by the diference is equal to the difference of squares", that is to say:
(
a
+
b
)
⋅
(
a
−
b
)
=
a
2
−
b
2
.
By applying this to our question, we obtain that:
(
3
a
−
4
)
⋅
(
3
a
+
4
)
=
(
3
a
)
