Question

Write a polynomial function in standard form with the given zeros.

x= 1,1,2

Steps please?

Answer 1

first you have to set all three factors up to equal 0

Answer 2

x = 1
x-1 = 0

Answer 3

since the zeros have to be at 1 and 2 (with a double root at 1), this must at least be a third degree polynomial...

y = (x-1)(x-1)(x-2)

multiply out the right side and write it in descending order with the highest degree first down to the least.

Answer 4

x= 2
x-2 = 0
