Question

Find K if X equal to 2 is the root of quadratic equation 2 by k x square - 5 x + 1 equal to zero

Answer 1

Answer:

Step-by-step explanation:

X = 2

2 / kx² - 5x + 1 = 0

2 / k(2)² - 5(2) + 1= 0

2 / 4k - 10 +1 = 0

On taking LCM

2 - 40k +4k ÷ 4k = 0

2 - 40 K +4 K = 0

2-36k = 0

2 = 36k

K= 2/36 = 1/18
