Question

Q21. Find the value of k for which the roots of the equations 3x- 10x + k = 0 are
reciprocal of each other.​

Answer 1

Step-by-step explanation:

putting x=0

so, 3×0 - 10×0 + k

0+k

k=0

Answer 2

Answer:

let roots of equation be x and 1/x

sum of roots =10/3(-b/a)

x+1/x=10/3

x^2+1 =10/3

x

3x^2+3=10x

3x^2-10x+3=0

.

so, k=3
