Question

find the value of k ,if x-1 is a factor of p(x)=2x^2+k x +√2​

Answer 1

Answer:

-2 - 2^1/2

Step-by-step explanation:

by factor theorem

2*(1)^2 + k(1) + 2^1/2 = 0

== k = -2 - 2^1/2

Answer 2

Answer:

√2 - 2.

Step-by-step explanation:

Use synthetic division. In the end, the remainder should be zero. While using synthetic division, the number that should be added to √2 to get a remainder 0 is k+2. Hence, k = √2 - 2.
