Answer:
x = 0, x = -4, and x = 6
Step-by-step explanation:
To find the zeros of this polynomial, we can begin by factoring out a common factor of each term. 'x' is a common factor. We can distribute this variable out, giving us:
f(x) = x(x²- 2x- 24)
Now, factor the polynomial inside of the parenthesis into its simplest form. Factors of -24 that add up to -2 are -4 and 6.
f(x) = x( x + 4) (x - 6)
From this, we can derive the zeros x = 0, x = -4 and x = 6.
Oh ok so the answer is .666666666666 etc infinite 6s
Answer:
n(B) = 1350
Step-by-step explanation:
Using Venn sets, we have that:
![n(A \cup B) = n(A) + n(B) - n(A \cap B)](https://tex.z-dn.net/?f=n%28A%20%5Ccup%20B%29%20%3D%20n%28A%29%20%2B%20n%28B%29%20-%20n%28A%20%5Ccap%20B%29)
Three values are given in the exercise.
The other is n(B), which we have to find. So
![n(A \cup B) = n(A) + n(B) - n(A \cap B)](https://tex.z-dn.net/?f=n%28A%20%5Ccup%20B%29%20%3D%20n%28A%29%20%2B%20n%28B%29%20-%20n%28A%20%5Ccap%20B%29)
![2290 = 1300 + n(B) - 360](https://tex.z-dn.net/?f=2290%20%3D%201300%20%2B%20n%28B%29%20-%20360)
![940 + n(B) = 2290](https://tex.z-dn.net/?f=940%20%2B%20n%28B%29%20%3D%202290)
![n(B) = 2290 - 940 = 1350](https://tex.z-dn.net/?f=n%28B%29%20%3D%202290%20-%20940%20%3D%201350)
So
n(B) = 1350
