x^3+6x^2+8x = 0\\\\\implies x^3+2x^2 +4x^2+8x =0\\\\\implies x^2(x+2)  +4x (x+2)   =0\\\\\implies (x+2)(x^2 +4x) = 0\\\\\implies x (x+2) (x+4)=0\\\\\text{Hence,} \\\\x = 0 ,-2,-4

Answer:

Option A: x=0, x=-2, and x=-4

Step-by-step explanation:

f(x)=x^3+6x^2+8x

0=x^3+6x^2+8x

0=x(x^2+6x+8)

0=x(x+2)(x+4)

x=0, x=-2, and x=-4

−−→AB=(xy)<br><br> What values should <br> x<br> and <br> y<br> take?
laiz [17]

The values of x and y are 2 and 0, respectively

The complete question is given below:-

−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?

<h3>How do determine the value of x?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

From the graph, we have the following highlights:

Point A is at:

A = 2

The point B is located at:

B = 0

The coordinate (x,y) is represented as:

(x,y) = (A,B)

So, we have:

(x,y) = (2,0)

Hence, the values of x and y are 2 and 0, respectively
