Answer:
Step-by-step explanation:
The zeros of the polynomial function are given us as -5,-1,2
If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:
f(x) = (x - α)(x - β)(x - ω)
where α = -5, β = -1, and ω = 2
<em>NB: To arrive at the answer, expand the brackets and after expansion, collect like terms to obtain the final answer</em>
First, we expand the equation:
Then, we combine certain terms in order to simplify them using trigonometry identities.
Note these identities:
Pythagoran relation:
Sum and Difference Formula/Identities:
Thus, if we apply these identities, the simplified equation would be:
Simplying further, the answer would be
![2[cos(A-B)+1]](https://tex.z-dn.net/?f=2%5Bcos%28A-B%29%2B1%5D)
