The zeroes of the function are 1 and 7 and multiplicity for zero 1 is two and for zero 5 is one.
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have a polynomial function:
f(x) = (x – 1)(x – 1)(x + 7)
We can write it as:
f(x) = (x – 1)²(x + 7)
Here at x = 1 the given function becomes zero and (x-1) repeats two times, so the multiplicity is 2, and for x = -7 the multiplicity is 1.
Thus, the zeroes of the function are 1 and 7 and multiplicity for zero 1 is two and for zero 5 is one.
