Question

if 2x - 1 is a factor of the polynomial 6x square + kx minus 2 then the value of k is​

Answer 1

Answer:

k=1

Step-by-step explanation:

2x-1 is a factor of the polynomial 6x²+kx-2 =0

Acc. to remainder theorem when we sub the factor value of x in given polynomial then the whole value is equal to zero

2x-1=0

x=1/2 sub in given polynomial

6(1/2)² + k/2 -2 = 0

3/2 +k/2 =2

[k+3]/2 = 2

k+3 = 4

k=1
