Question

if x is equal to 2 is a root of quadratic equation 2 by k x square - 5 by k x + 1 is equal to zero then find the value of k​

Answer 1

Answer:

k=2

Step-by-step explanation:

2/k*x²-5/k * x+1=0

Multiply by k

2x²-5x+k=0

x=2 iis a root

so putting x=2

2*2^2-5(2)+k=0

8-10+k=0

k=10-8=2
