First you graph it using a graphing calculator, you look at the table of values to find out one point in which y= 0. The first one that comes up is when x=1.
If you don't have a graphing calculator you can use trial and error by inputing some numbers into x until you get y= 0.
Once you have an x value which makes y=0, you can start factorizing it.
you divide 6x3 +4x2 -6x - 4 into (x-1) which is when y =0
to get 6x2+10x+4
This can be used to write the polynomial as (x-1)(6x2 +10x+4)
you then factorize the second bracket, 6x2 +10x+4.
you can take the 2 outside to give you 2(3x2 +5x+2)
you can factorize this to become 2(3x+2)(x+1)
Now you just substitute your factorized second bracket into your unfactorized second bracket to give you 2(3x+2)(x+1)(x-1).
From this you can deduce that k= 1
Answer:
15.5
Step-by-step explanation:
Answer: OPTION C.
Step-by-step explanation:
The missing options are:

In order to solve this exercise you need to remember the following:
1. The Distributive property states that:

2. The multiplication of signs:

In this case the exercise gives you the following equation:

Since you need to solve for the variable "x" in order to find its value, the first step you must apply in the in the procedure is to eliminate the parentheses applying the Distributive property.
Then, you must multiply everyting inside the parentheses by
.
Therefore,based on the explanation, you know that the correct use of the Distributive property is:

Answer: 10?
Step-by-step explanation:
I'm guessing the problem based off your description
5 (1/2) x 4 = X
2.5 x 4 = X
X = 10
