Proofread your questions before you post them. I assume in the second instance, you mean x^2+bx+c.
Positive times negative = negative
Positive times positive or negative times negative = positive.
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?
