Question

If one of the zeroes of the quadratic polynomial (k-1)x2

+ kx +1 is -3, then the value of k is​

Answer 1

Answer:

(k-1)2+kx+1=0

(k-1)2+k(-3)+1=0

2k-2-3k+1=0

2k-3k-2+1=0

-k-1=0

k=-1

Answer 2

here is your answer mate.

to find the value of kilometers you just have to put the value of x in the equation.

(k-1)x^2 + kx +1=0

(k-1)(-3)^2 + k(-3) +1=0

(k-1)9 - 3k +1 = 0

9k -9 -3k + 1 = 0

6k - 8= 0

6k = 8

k = 8/6
