Question

If one root of the equation 2x²- kx +6=0 is 2, then the value of k is​

Answer 1

Answer:

7

Step-by-step explanation:

One root of the equation 2x²-kx+6=0 is given 2

It will satisfy the equation

=> 2(2)²-k(2)+6=0

8-2k+6=0

=> k=7

Answer 2

Answer:

I hope sure your happy

Step-by-step explanation:

Since x=2 is a value of the equation

2x 2+kx−6=0

2k+2=0

k=−1

Putting k =-1 in the given equation, we get,

2x 2 −x−6=0

(x−2)(2x+3)=0

x=2,− 2/3

Hence, the other value is − 2/3
