Provide an appropriate response.In factoring a trinomial in y as (y + a)(y + b), what must be true of a and b, if the coefficient of the last term of the trinomial is negative?
What will be an ideal response?
The numbers a and b must have different signs (one positive and one negative).

Three players (one divider and two choosers) are going to divide a cake fairly using the lone divider method. The divider cuts the cake into three slices (s1, s2, and s3).Suppose the choosers value the slices as follows:
Which of the following is a fair division of the cake?
A. Chooser 1 gets s1; Chooser 2 gets s2; Divider gets s3. B. Divider 1 gets s2; Choosers 1 and 2 divide s1 + s3 using the divider-chooser method. C. Chooser 1 gets s2; Chooser 2 gets s3; Divider gets s1. D. Divider 1 gets s1; Choosers 1 and 2 divide s2 + s3 using the divider-chooser method. E. none of these
