Question 1190148
<font color=black size=3>
You have used the remainder theorem correctly, and your computations are correct as well. Nice work.


Getting a remainder of zero on the first problem shows that x+1 is a factor of x^3 + x^2 -4x - 4


Getting a nonzero remainder on the second problem shows that x+3 is not a factor of 2x^3 -11x^2 + 12x - 4
