Question

if one of the zeroes of the quadratic polynomial (k-1)X2+2kx+3is1 then find the value of k
​

Answer 1

Answer:

-1/4

Step-by-step explanation:

Since one of the zero of the quadratic polynomial is 1 which means putting the value of x=1 in polynomial will make it 0.

(k-1)×2+2kx+3=0. (putting x=1)

2k-2+2k×1+3=0

4k+1=0

4k=-1

k=-1/4
