Answer:
We have
y
=
(
x
+
3
)
(
x
2
−
3
x
+
9
)
.
We need to expand this using the Distributive Property.
y
=
(
x
+
3
)
(
x
2
−
3
x
+
9
)
=
x
⋅
(
x
2
−
3
x
+
9
)
+
3
⋅
(
x
2
−
3
x
+
9
)
.
We multiply these through to get
y
=
x
3
−
3
x
2
+
9
⋅
x
+
3
⋅
x
2
−
9
x
+
27
.
Collecting like terms we have
y
=
x
3
+
27
.
I HOPE IT HELP YOU....
