Question

what is the value of K if x-√2 is a factor of p(x) = 4x²-3x+2 ?​

Answer 1

Answer:

Correct option is

A−6

Given expression is x 3 +kx 2 +12x−8=0

x−2 is a factor of the given expression.

So, x=2

Substitute in the equation, we get

2

3

+k(2)

2

+12(2)−8=0

⇒8+4k+24−8=0

⇒4k=−24

⇒k=−6
