Answer:
x ∈ (-∞ , -2) ∪ (1, 3)
Step-by-step explanation:
The expression is already factored. Note that for the polynomial that appears in the numerator there are 2 roots:
For the polynomial that appears in the denominator there is 1 root:
Note that does not belong to the domain of f(x) because it zeroes the denominator of the function and the division between zero is not defined.
With these three roots we do the study of signs to find out when
Observe the attached image
Note that:

Finally, we have the solution:
x ∈ (-∞ , -2) ∪ (1, 3)
Answer:
8
Step-by-step explanation:
45 divided by 5 is 9 and what you do on the to you do on the bottom which means you would do 40 divided by 5 which you would get 8 as your answer.
Answer:
another way to write this is 1:3
Answer:
C
Step-by-step explanation:
Here's a trick:
Find the <u>last</u><u> </u>number of the equation and look at your factors to see which numbers you can multiply to get that answer
in this case the last number of x^3-8x^2+17x-10 is -10
*IF IT HAS A NEGATIVE, ALWAYS REMEMBER TO INCLUDE IT*
Then look at the options and see what numbers can get you -10 but include the factor that they give you.
in this case C has the numbers as -1×-5×-2 gives you -10
now to check by using the box method, which is much easier to do, and put pick 2 of those factors and check if it's right
