Find the equation in factored form zeros=-2 and 2 with vertex (0,-4)

Step-by-step explanation:

Factored form of quadratic equation:

x₁, x₂ - zeros

We have zeros: x₁ = -2 and x₂ = 2. Substitute:

We have the vertex (0, -4). Put the coordinates of the vertex to the equation:

            divdie both sides by (-4)
