Question

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

Open in App

Solution

$p (x) = k x^{2} - \sqrt{2} x + 1 p (1) = k - \sqrt{2} + 1 = 0 \Rightarrow k = \sqrt{2} - 1$

Find the value of k, if x - 1 is a factor p(x) and if p(x)=kx2−√2x+1

p(x)=kx2−√2x+1p(1)=k−√2+1=0⇒k=√2−1

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

$p (x) = k x^{2} - \sqrt{2} x + 1 p (1) = k - \sqrt{2} + 1 = 0 \Rightarrow k = \sqrt{2} - 1$
