Best ResponseYou've already chosen the best response.01,3,5,15 1,3,5,15 lets try x=3 3  1 6 10 2 15 0 3 9 3 15  1 3 1 5 0 <remainder is zero, this is a solution (x3)  lets try x = 1 1  1 3 1 5 0 1 4 5  1 4 5 0 < remainder is zero, this is a solution. (x+1)(x3) is what we got so far..  the rest is a quadratic that can be figured out the normal way:

Best ResponseYou've already chosen the best response.0x^2 4x +5 = 0 16  4(5) = 16  20 = 4... there are no more real solutions the answer is: (x3) (x+1) (x^2 4x +5) since the quadratic is zeroless that leaves: x = 3 or x = 1 as our solutions.
