Explanation:
To begin, set up the expressions next to each other in parenthesis
(
x
+
5
)
(
2
x
2
+
7
x
−
10
)
Now, you are going to distribute the first term in the first set of parenthesis throughout each term in the second set of parenthesis:
(
x
+
5
)
(
2
x
2
+
7
x
−
10
)
=
=
x
(
2
x
2
+
7
x
−
10
)
+
5
(
2
x
2
+
7
x
−
10
)
First, distribute
x
across
2
x
2
,
7
x
, and
−
10
So, multiply
x
by each of those terms to get:
2
x
3
+
7
x
2
−
10
x
Next, distribute the
5
throughout the set of parenthesis
5
(
2
x
2
+
7
x
−
10
)
=
10
x
2
+
35
x
−
50
Now add the 6 terms to get the final answer.
