Question

kx square +3x-4=0 are equal roots find the value of k
give me answer in step by step ​

Answer 1

Answer:

-9/16

Step-by-step explanation:

Roots of the equation are equal so, discriminant of the equation= 0

Discriminant=

${b}^{2} - 4ac$

Here D= 0

So,

${3}^{2} - 4 \times k \times ( - 4) = 0$

Or, 9+16k= 0

So, k= -9/16

Please mark me as brainliest.

Answer 2

Step-by-step explanation:

here kx2+3x-4=0 have equal roots

so , b2-4ac=0

a=k, b=3 , c= -4

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

9+16k=0

16k=-9

k= -9/16
