Asked by Amy L

Am not understanding this. Could someone please explain to me.

If x^2+bx+c is factorable and c is negative, then the signs of the last term factors of the binomials are opposite, why?

If x^2+bc+c is factorable and c is positive, then the signs of the last term factors of the binomials are the same, Why?

Proofread your questions before you post them. I assume in the second instance, you mean x^2+b<B>x</B>+c.

Positive times negative = negative

Positive times positive or negative times negative = positive.
