Question

Find the value of k if x-2 is a factor of the polynomial kx square - root 2x + 1

Answer 1

Hey there !

Thanks for the question !

Here's the answer !

Given that, x - 2 is a factor

=> x = 2

Equation = kx² - √2 x + 1 = 0

Substituting x = 2 we get,

=> k ( 2 )² - √2 ( 2 ) + 1 = 0

=> 4k - 2√2 + 1 = 0

=> 4k = 2√2 - 1

=> k = ( 2√2 - 1 ) / 4

Hope my answer helped !
