If (x+4) is a factor of -x2-11x-w = 0, then the value of w is:

Question

a.-60

b. -28

c. 28 or

d.60

Answer 1

When you use long division to divide x+4 into -x^2 -11x -w, you get
-x + (-7x -w)/(x+4)
Ask yourself what 4 has to be in order for (-7x -w)/(x+4) to be equal to a constant.

Answer 2

3x3 − 2x2 + 75x − 50
