Just multiply every side by 4
Yes, no x values repeated
The value for x that is a double root of this function is x = -1
<h3>How to determine the double root?</h3>
The function is given as:
f(x) = x^3 - 3x - 2
From the graph of the above function (see attachment), we have the following highlights:
- The curve crosses the x-axis at x = 2
- The curve touches the x-axis at x = -1
The point that it touches the x-axis is the double root point
Hence, the value for x that is a double root of this function is x = -1

Answer:
The zeros are x=7 and x= -6
Step-by-step explanation:
In order to find the zeros of a function with factors, we have to equate the factors to zero.
So x-7 = 0
and
x+6 = 0
Then we solve for x in each equation,
x= 7 and x= -6
These values are the zeros
