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)

Reorder the steps for finding all roots (zeros) of polynomials.

• Use the quadratic formula to find the remaining roots.

• Graph the function and identify rational roots.

• Use synthetic division again (if needed) with another rational root until you get a quadratic expression.

• Use synthetic division with one of the rational roots.

What are the zeros of the graph?

• -4, -1, 2, 1 multiplicity 2

• -4, -1, 1, 2

• 4, 1, -2, -1 multiplicity 2

• 4, 1, -1, -2
