The polynomial equation is P(x) = (x + 1)(x + 1)(x + 1)(x - 4)
<h3>How to determine the polynomial?</h3>
The given parameters are:
- Degree = 4
- Roots = -1 (three times) and 4
A polynomial equation is represented as:
P(x) = (x- Root)
So, we have:
P(x) = (x - (-1))(x - (-1))(x - (-1))(x - 4)
Open the inner brackets
P(x) = (x + 1)(x + 1)(x + 1)(x - 4)
Hence, the polynomial equation is P(x) = (x + 1)(x + 1)(x + 1)(x - 4)
