Question

if one of the zeroes of the quadratic polynomial (k-1)x^2+kx+1 is -3, then the value of k is ?

Answer 1

Answer:

The other zero is 2/3.

Step-by-step explanation:

x(3)=(k-1)3²+3k+1

=>9k-9+3k+1

=>12k-8=0

=>12k=8

=>k=8/12

=>k=2/3

The another zero of that quadratic polynomial is 2/3.

And that's all your answer

Answer 2

Answer:

k=2/3

Step-by-step explanation:

x(3)=(k-1)3²+3k+1

=>9k-9+3k+1

=>12k-8=0

=>12k=8

=>k=8/12

=>k=2/3
