Given:
The function is:

It is given that -1 is a zero of the given function.
To find:
The other zeroes of the given function.
Solution:
If c is a zero of a polynomial P(x), then (x-c) is a factor of the polynomial.
It is given that -1 is a zero of the given function. So,
is a factor of the given function.
We have,

Split the middle terms in such a way so that we get (x+1) as a factor.



Again splitting the middle term, we get



For zeroes,
.

and
and 
and
and 
Therefore, the other two zeroes of the given function are
and
.
Answer:
0%
Step-by-step explanation:
Don't quote me on that but I'm pretty sure
Use similar volume to calculate
which is the (ratio of edges)^3 = (ration of volume)
so just put the numbers in, let the volume of smaller pyramid be y.
(3/4)^3 = y/320
27/64 = y/320
y=135in3
the greatest is 10 and the least is one but I don't know for sure but I don't know if that what you looking for
