Answer:
my answer is A. you only need substitute n from 1 to 4
Step-by-step explanation:
if x-4 is a factor of 2x^3 + x^2- 26x - 40
then f(4) = 0
f(x) = 2x^3 + x^2- 26x - 40
f(4) = 2(4)^3 + (4)^2 - 26(4) - 40
f(4)= 2(64) + 16 - 104 - 40
f(4) = 128 + 16 - 104 - 40
f(4) = 0
hence factorize completely is the photo
The commutative property implies that, the order of multiplication is not important.
is true
Commutative property of multiplication states that:
If 
The expression is given as:

To get the commutative expression, we simply change the position of each factor in the expression.
So, some possible equivalent expressions are:



There are several other equivalent expressions.
From the list of options;
