Question

If x=4 is one root of the quadratic equation x²-10kx-6=0 then find value ok k.​

Answer 1

Answer:

1/4

Step-by-step explanation:

Suppose

p(x) = x²-2kx-6=0

x= 4 is one root of the quadratic equation

Remainder = p(4) = 0

=> p(4)=0

=> (4)²-10k(4) - 6 = 0

=> 16-40k-6=0

=> -40k=6-16

=> - 40k = -10

=> k=10/40

=> k=1/4
