Hello there,
Zeros are the solutions to a specific polynomial
In the function below
p(x) = x(x-5)(x-2)(x+3)
The zeros that we have are
1) x-5 and that results in x = 5
2) x - 2 and that results in x = 2
3) x+3 and that results in x = -3
4) x = 0
So the smallest zero is the lowest solution..
Obviously, it is -3
Thus the lowest zero is x+3
Hope that helps.
