Consider the polynomial
p
(
x
)
=
x
3
+
2
x
2
−
7
x
+
4
p(x)=x^{3}+2x^{2}-7x+4
p
(
x
)
=
x
3
+
2
x
2
−
7
x
+
4
. Which of the following explains why
(
x
−
4
)
(x-4)
(
x
−
4
)
is NOT a factor of
p
(
x
)
p(x)
p
(
x
)
? a) Because
p
(
−
4
)
=
0
p(-4)=0
p
(
−
4
)
=
0
. b) Because the degree of
p
(
x
)
p(x)
p
(
x
)
is 3. c) Because
p
(
4
)
≠
0
p(4)\neq0
p
(
4
)
=
0
. d) Because
p
(
4
)
=
0
p(4)=0
p
(
4
)
=
0
.
