Answer:
f(x) = x³ +3x² -6x -18
Step-by-step explanation:
In order for there to be a root of √6, there must be a factor of (x-√6). In order for there to be rational coefficients, there needs to be another factor of (x+√6) in the minimal polynomial. Then the minimal polynomial with the required roots is ...
f(x) = (x +3)(x -√6)(x +√6) = (x +3)(x² -6)
f(x) = x³ +3x² -6x -18
add them both then you get the awnser if the four is not a negative. if the four is a negative use division.
Answer:19+3x
Step-by-step explanation:
4+3(5+x)
Open bracket
4+15+3x
19+3x
Answer: The required value is
Step-by-step explanation: The given functions are:
We are given to find the value of 
We know that, if s(x) and t(x) are any two functions of a variable x, then we have
Therefore, we have
Thus, the required value is
