c.
Answer to Problem 52E
Explanation of Solution
Calculation:
Consider the polynomial function
The objective is to find the real zeroes of the given polynomial function.
To find the real zeros first set the polynomial equal to zero and if possible factorize the polynomial.
The polynomial in equation form is
Either
Hence, the real zeros are
d.
Compare the results of part (c) with those of part (b).
d.
Answer to Problem 52E
The solution of (b) and solution of (c) are the same.
Explanation of Solution
Calculation:
Consider the polynomial function
The objective is to compare the solution of (b) and solution of (c).
Hence, the solution of (b) and solution of (c) are the same.
