Does the equation y = (x – p)(x – q) intercept the x-axis a

[DavidW550]

This makes sense now. Thank you, Ron.

the point is that p and q are unknowns.

e.g., in statement 1, you have pq = –8.
• if one of p, q is 2 (and the other, therefore, is –4), then, yes, the point (2, 0) is on the curve.
• if p and q are any other numbers that multiply to 8, then the point (2, 0) is not on the curve.
so, statement 1 is not sufficient.
etc.

you can't use the QUESTION as though it were a FACT!
