Question

Find the value of k, for which one root of the quadratic equation kx²-14x+18=0 is 10.​

Answer 1

Answer:

k = 33/25

Step-by-step explanation:

For the quadratic equation kx²-14x+8 = 0,

one root is 19

So, x=10 must satisfied to the quadratic equation.

=> k(10)²-14(10) +8 = 0

=> 100k-140+8 = 0

=> 100k = 140-8

=> 100k=132

=> k=132/100

=> k=66/50

=> k=33/25
