Answer:
x = -5/2, -1, or 3
Step-by-step explanation:
The quadratic factor can be factored further to give ...
p(x) = (2x +5)(x +1)(x -3)
The zeros of p(x) are the values of x that make the factors zero:
2x +5 = 0 ⇒ x = -5/2
x +1 = 0 ⇒ x = -1
x -3 = 0 ⇒ x = 3
The zeros of the polynomial are x = -5/2, x = -1, or x = 3.
