The value of k for which kx^2-4x+4=0 has real equation and equal root​

Answer»

☆SoluTion =》

Answer:-

k=1

Given =》

▪︎ kx²-4x+4=0

To find=》

value of k

Explanation =》

kx²-4x+4=0

On comparing to the GENERAL FORM ax² +bx+C=0

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

for REAL and equal roots

D=0 ( D= b²-4ac)

b²-4ac=0

(-4)²- 4× k×4=0

16- 16k=0

-16k=-16

k= -16/16

k=1

value of k is 1
