Observe the linear factors to see that
−14 with multiplicity2
1 with multiplicity5
Explanation:
Note that linear factors correspond to zeros. The product of several factors is zeros if and only if at least one of the factors is zero.
So we can observe that
−14 with multiplicity2
1 with multiplicity5
Here's a graph of
graph{5(x+1/4)^2(x-1)^5 [-0.62, 1.88, -0.54, 0.71]}
