Question

if one root of quadratic equation 4x square - 4kx + K + 5 equal to zero is 1 what will the value of k​

Answer 1

Answer:

k=3

Step-by-step explanation:

if one root is 1 then put the value of X=1 in the equation

therefore,

4(1)²-4k(1)+k+5=0

4-4k+k+5=0

9-3k=0

3k=9

k=3

therefore value of k is 3

Answer 2

Answer:

4x^-4kx+5
