You are told that a third powered polynomial has zeroes at -1, 2, 5. Part A. Write the three factors of the polynomial

Part B. Write the polynomial in standard form

a) factors of polynomial are: (x+1)(x-2)(x-5)

b) the required polynomial in standard form is:

Step-by-step explanation:

The polynomial has zeros at -1,2,5

Part A) Write the three factors of the polynomial

we have x=-1, x=2 and x=5 as zeros of polynomial

so factors will be:

(x+1)=0, (x-2)=0, (x-5)=0

So, factors of polynomial are: (x+1)(x-2)(x-5)

Part B) Write the polynomial in standard form

For finding polynomial, we will multiply all the factors i.e

(x+1)(x-2)(x-5)

So, the required polynomial in standard form is:
