Question

The quadratic expression x2−2x−35 can be factored into (x+5)(x−7) . Which ordered pairs represent the zeros of this expression’s related quadratic function?

Answer 1

(-5,0) and (7,0)

Explanation:

You are being asked to find "zeros", so just keep in mind that

zeros ARE roots ARE solutions ARE x-intercepts.

(there are tiny, technical differences bc math reasons, but on a simple overview, they are all the same thing!)

Set equal to zero and solve.

"ordered pairs" means write the answer like a point (x,y) We found the x when y is zero. See image.
