Answer :

The quadratic equation is y = x^2 - x - 6

How to use the zero product property to create a quadratic equation?

The given parameters are

x-intercepts: x=-1 and x=3

Rewrite properly as

x1 = -2 and x2 = 3

By zero product property, the quadratic equation is

y = (x - x1) * (x - x1)

This gives

y = (x + 2) * (x - 3)

Expand

y = x^2 + 2x - 3x - 6

Evaluate the difference

y = x^2 - x - 6

Hence, the quadratic equation is y = x^2 - x - 6
