Question

If x=5,then find the value of k,of the equation kx²-14x-5=0​

Answer 1

Step-by-step explanation:

k*5*5-14*5-5=0

25k-70-5=0

25k=75

k=75/25=3

Answer 2

Answer:

The value of k = 3

Step-by-step explanation:

Kx^2 - 14x -5=0

K × 25 - 14 × 5 - 5 = 0

25k - 70 - 5 = 0

25k -75 = 0

25k = 75

k= 75/25

k= 3
