Question

What is the value of k if (x – 1) is a factor of ka² -√2x+1?​

Answer 1

Answer:

√2 - 1

Step-by-step explanation:

x - 1 is factor of kx² - √2x + 1.

So, let x - 1 = 0.

∴ x = 1

Putting x = 1 in kx² - √2x + 1,

k(1)² - √2(1) + 1 = 0

k - √2 + 1 = 0

∴ k = 0 - (-√2 + 1) => √2 - 1     (Minus and minus combine to become plus.)
