Question

find the value of K, if x=2 is a solution 2x^2-kx-6?​

Answer 1

put x=2 in given quadratic equation

2x^2-kx-6=0

2(2)^2-k(2)-6=0

2x4-2k-6=0

8-2k-6=0

2-2k=0

2=2k

k=2/2

k=1

hope it help you

Answer 2

Answer: UR REQUIRED ANSWER ;-

QUESTION :

2x² - kx - 6

SOLUTION :-

x =  2

so , by putting the value of x in the equation ;

2 ( 2)² - k × 2 - 6 = 0

⇒ 8 - 2k - 6 = 0

⇒2 - 2k = 0

⇒-2k = -2

⇒ k = 1 .

so , the value of k is 1 .
