Find the value of k, if x - 1 is a factor of p(x)
$p (x) = k x^{2} - 3 x + k$

Open in App

Solution

(x -1) is a factor, so we substitute x = 1 in each case and solve for k by making p(1) equal to 0.
$p (x) = k x^{2} - 3 x + k p (1) = k - 3 + k = 0 \Rightarrow 2 k - 3 = 0 \Rightarrow k = \frac{3}{2}$
