you are about to factor a quadratic equation involving some X2's,someX's and a plain number. you see that the

Question

X's is negative, and the sign in front of the plain number is positive. this tells you that when you find the twobrackets of factors,_______.
a.they will both contain a minus sign
b.they will both contain a plus sign
c.one will contain a minus sign and the other will contain a plus sign
d.one will contain a zero

Answer 1

Your equation would look like x^2-ax+b. Which means when you solve the equation you would two answers one of which will contain a plus sign other will contain a minus sign since the middle term is negative. Thus the answer is C.

Answer 2

a.they will both contain a minus sign

Answer 3

answer is A. looking at the equation x^2-ax+b, when you factor it it should look something of the form (x-c)(x-d). This means that FOILing would produce x^2-cx-dx+cd. Then ax=cx-dx and b=cd and ax would be negative and b would be positive.
