Question

(3).Find the value of k, if x-1 is a factor of p(x) in each of the following cases...........

(ii) p(x) =2x2+kx+√2​

Answer 1

Answer:

Step-by-step explanation:

x - 1 = 0

  x = 1

p(x) =$2x^{2}$ +kx +$\sqrt{2}$

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

      = 2 + k + $\sqrt{2}$

2+ k +$\sqrt{2}$ = 0

     k       = -2 -$\sqrt{2}$

Hope this helps....
