Question

select the correct verbal description for the expression below. x(2y+4z)^2


a. the product of x and a factor depending on x

b. the sum of x and a factor not depending on x

c. the sum of x and a factor depending on x

d. the podcut of x and a factor not depending on x

Answer 1

Consider the expression $x(2y+4z)^2.$ This expression is equivalent to the expression

$x\cdot (2y+4z)^2.$

This expression contains two factors:

1 factor: $x;$

2 factor: $(2y+4z)^2.$

The second factor does not contain x (is not depending on x), then  the expression $x(2y+4z)^2$ is the product of x and a factor not depending on x.

Answer: correct choice is D
