Answer to Problem 49E
The real solutions are
Explanation of Solution
Given Information:
The given cubic polynomial is
Formula Used:
Synthetic Division: Use the below method to find the factor.
Calculation:
The cubic polynomial is
The factor of the cubic polynomial is
Rewrite the factor is:
Divide the polynomial
Thus, the remainder is 0, so,
Now, the quadratic equation becomes,
Take 2 as common.
Split the middle term.
Take x common from the first two terms and
That is,
Thus, the factors of
Hence, the real solutions are
