Finding the Zeros of Factored Polynomials

Find the zeros of the polynomials

• A

• B

• C

• D

Which of the following is NOT a possible rational root. 

• A

• B

• C

• D

Given one complex zero use the conjugate root theorem to find another.  Zero is 7-5i

• -7+5i

• 7-5i

• -7-5i

• 7+5i

Find all zeros.

• x= 3,1,1/3

• x= -3, -1, -1/3

• x = -3, 1, 1/3

• x = 3, -1, -1/3

Given one complex zero use the conjugate root theorem to find another.  Zero is: -12-8i

• 12+8i

• -12+8i

• 12-8i

• -12-8i

Identify the zeros

• x=2, x=6, x=-4

• (x+2)(x+6)(x-4)

• (x-2)(x-6)(x+4)

• x=-2, x=-6, x=4

What are the zeros of the function?

• 4,1

• 3,1,-2,-5

• -3, -1, 2, 5

• -2,4

Find the zero(s) of the function.

• x = 1

• x = -3

• x = {-1, 3}

• x = 2

Find the root(s) of the function.

• x = 3

• x = {-3, -1, 2}

• x = {-3, 2}

• x = -1

What is the equation in factored form of this graph?

• f(x) = (x-4)(x-1)²(x+2)(x+4)

• f(x) = (x-4)(x+1)²(x+2)(x+4)

• f(x) = (x-4)(x-1)²(x-2)(x+4)

• f(x) = (x+4)(x+1)²(x-2)(x-4)
