Question

If one root of the quadratic equation 2x2 + kx – 6 = 0 is 2, find the value of k also find the
other root. dont irrevelant ans or questions ok you correct only answer​

Answer 1

Answer:

Hello

Step-by-step explanation:

Since x=2 is a root of the equation

2x2+kx−6=0

2k+2=0

k=−1

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

2x2−x−6=0

(x−2)(2x+3)=0

x=2,−23

Hence, the other root is −23.

Answer 2

Step-by-step explanation:

Since x=2 is a root 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,− 3/2

Hence, the other root is − 3/2
