Question

Find k, if the root of the Quadratic equation kx²kx²-4x+4=0 are equal​

Answer 1

Answer:

K = 1

Step-by-step explanation:

Use discriminant formula b²-4ac = 0 for equal roots you will get your answer.

Answer 2

k= 1

Step-by-step explanation:

comparing the given eq. with ax²+ bx + c = 0,

a = k ,b = -4 ,c = 4

therefore, b²- 4ac = (-4)² - (4× k× 4)

=16 - 16k

16k= 16

k = 16 / 16

k = 1
