Question

4x^2-3k+1=0 and roots are real and equal then k=?​

Answer 1

Answer:

4/3

Step-by-step explanation:

roots are real mean

by quadratic formula

b^2-4ac=0

(-3k)^2-4*4*1=0

9k^2-16=0

k^2=16/9

k=4/3

its the correct answer

please mark it as brainlliest   :-)

Answer 2

Step-by-step explanation:

For real and equal roots,

Discriminant equal to zero

i.e,

D=0

b^2-4ac = 0

(-3k)^2- 4(4)(1)= 0

9k^2=16

k^2=16/9

k= ± 4/3
