Question

if the root of the equation (k-1) x2-10x+3=0 is the resiprocal of the other then the valueof k is​

Answer 1

Answer:

k=7

Step-by-step explanation:

let value of x be 1.5

(k-1)×2-10x+3=0

2k-2-15+3=0

2k-14=0

2k=14

k=14/2

k=7

Answer 2

Answer:

• let us take root of equation=Alpha
• so,other root=1/alpha
• third step,we take product root=c/alpha
• fourth step,we take as
• alpha×1/alpha=3/(k-1)
• 1=3/k-1
• k-1=3
• k=3+1
• k=4
