Answer:
3
x
2
+
10
x
−
8
first multiply
3
with
−
8
and we get
−
24
then find two numbers that if we add or subtract we get
+
10
and if we multiply we get
−
24
and the numbers are
+
12
and
−
2
then we place those numbers as follow :-
3
x
2
+
12
x
−
2
x
−
8
then we group them
(
3
x
2
+
12
x
)
(
−
2
x
−
8
)
now take the common factor out.
3
x
(
x
+
4
)
−
2
(
x
+
4
)
then group the numbers outside of the brackets
(
3
x
−
2
)
(
x
+
4
)
and that is the answer
