Pls explain value of k ???:

1. Find the value of k for which the system of equations 2x +3y =8 and 3x -ky =4 is inconsistent.

2. If the sum of the zeroes of the quadratic polynomial kx2 -2x +3k is equal to their product, find the value of k. 

  • -2
a1/a2 = b1/b2 not = c1/c2
​=2/3=3/k 
=2k=9
therefore k = 9/2 or 4.5
(for verification 9/2 is better)
