Remember by the theory of polynomial is a factor of only if 2 is a zero of this polynomial, thus, , thus, thus, .Originally Posted by aussiekid90
Now for the check, the polynomial is which factors into thus, it works.
I had a problem that states: "Determine all values of k such that x^2-kx-6 can be factored by x-2." I had no idea what the answer was and left it blank. Can you please tell me how i would go through doing a problem like that. Thank you.
