a.
Verify the factors of
a.
Answer to Problem 70E
Explanation of Solution
Calculation: Here, we will consider the following function and factors of
Now, we will divide
Hence, the remainder is zero so
Now, we will again divide
Hence, again the remainder is zero so
b.
Find the remaining factor(s) of
b.
Answer to Problem 70E
Explanation of Solution
Calculation: Here, from the above synthetic division we will rewrite the polynomial
Hence, the remaining factor is
c.
Write the complete factorization of
c.
Answer to Problem 70E
Explanation of Solution
Calculation:
As,
Thus, the complete factorization of the function
Hence, the complete factorization of the function
d.
List all real zeros of
d.
Answer to Problem 70E
Explanation of Solution
Calculation:
Here, to find the zeroes of
Now, we will set the first factor to zero and solve for
Now, we will set the second factor to zero and solve for
Now, we will set the third factor to zero and solve for
Hence, the zeroes of the function are
e.
Confirm your results by using a graphing utility.
e.
Answer to Problem 70E
Explanation of Solution
Calculation:
Here, the graph of the function
Now, from the above graph we have observed that the graph of the function intersects
Hence, the results are verified.
