Question

Sum of the zeroes of 3x²+(2k+1) x + 12 is -7 .Then the value of k is

Answer 1

Answer:

-23/3

Step-by-step explanation:

let us take ,

3xsquare + {2k +1 }x+12 as p{x}

p{x} = p (1)

p(1)= 3 + (2kx+x)+12 = -7

3+(2k)+(1)+12= -7

3+2k+1+12= -7

2k + 16 = -7

2k = -7 -16

=-23

k = -23 / 2
