Answer:
(x+1)(x-14)(x+3)
Step-by-step explanation:
The first step in factorising polynomials is to find the smallest factor first. The way to do this is with trial and error. Lets see if x+1 is a factor.
According to the factor theorem, (x-a) is a factor of P(x) if and only when P(a) = 0
In this case we will use f(x) = ((x)^3)-((10x)^2)-53x-42
f(-1) = 0
Therefore (x+1) is a factor of the polynomial.
Now we divide the polynomial with (x+1) via long division to get (x^2)-11x-42.
We now factorise (x^2)-11x-42 using whatever method you would like. I'm going to use the AC method, where we find a number that multiplies to AC and adds to B, In this case AC = -42, and B = -11.
Therefore (x^2)-11x-42 factosied is (x-14)(x+3)
Now merge (x+1) with (x-14)(x+3)
The final answer is (x+1)(x-14)(x+3)

Step-by-step explanation:
hope it's okay to you
1) What is the mean of the data set:
The best plot is the dot plot. Sum the values of each dot and divide by the number of dots.
2) What is the median of the data set:
Use the box plot. The median is the value in the middle of the rectangle. That is 8.
3) What is the interquartile range:
Use the box plot. The interquartile range is the length of the rectangle. That is 10 - 6 = 4
4) How many members use the facility 10 days a month:
Use the box plot. The answer count how many dots are over the number 10. That is 2.
