Question
If the remainder is 0 when one polynomial is divided by another, the divisor is a factor of the divided. Find the value(s) of $c$ for which $x-1$ is a factor of each polynomial.$$x^{2}-4 x+c$$
Step 1
This means that when we divide $x^{2}-4x+c$ by $x-1$, the remainder should be 0. We can use synthetic division to find this value. Show more…

If the remainder is 0 when one polynomial is divided by another, the divisor is a factor of the divided. Find the value(s) of $c$ for which $x-1$ is a factor of each polynomial. $$2 x^{2}-3 c x-8$$
From the remainder theorem, the polynomial $x-c$ is a factor of a polynomial function $P(x)$ if $P(c)$ is what value?
