Question

If one of the zeroes of the quadratic polynomial (k–1) x2
+ k x + 1 is –3, then the
value of k

Answer 1

Heya!!!

X = -3

( k -1 ) ×9 -3k +1 = 0

6k = 8

k = 4 / 3

Have a nice day ahead.

Answer 2

HEY USER ………

HERE IS UR ANSWER ………

( k - 1 ) x^2 + k x + 1

( k - 1 ) 9 - 3 k + 1

9 k - 9 - 3 k + 1

6 k - 9 + 1 = 0

6 k - 8 = 0

6 k = 8

k = 8 / 6

k = 4 / 3
