If the zeros of a quadratic equation are −2 and 3, the equation can be written as

• (x − 2)(x + 3) = y

• (x + 2)(x − 3) = y

• (x + 2)(x + 3) = y

• (x − 2)(x − 3) = y

Keith found the zeros of a graph to be \frac{1}{2} and -3 . What would the equation look like in factored form?

• y = (2x + 1)(x + 3)

• y = (2x – 1)(x + 3)

• y = (2x – 1)(x – 3)

• y = (2x + 1)(x – 3)
