Question

Find the value of k for which x=2is a root of the equation x²-kx+6=0.Also find the other root.

Answer 1

Step-by-step explanation:

putting x =2 which is given . then get the value of k and after that to find another root put value of k and solve by factorisation.

Answer 2

Step-by-step explanation:

x2 + kx + 6 = 0

Put x = 2 in the above quadratic equation -

(2)2- K(2) +6 = 0

4 - 2k + 6 = 0

-2k + 10 = 0

-2k = -10

k = -10 /-2

k = 5
