Question

If root 2/3 is a solution of equation 3x2+ mx + 2 = 0 find the value of m.​

Answer 1

Answer:

m = (-4 Root 2)

Step-by-step explanation:

If root 2/ 3 is a solution of 3x^2 + mx + 2 = 0 then

3 (root 2/ 3)^2 + m (root 2/ 3) + 2 = 0

=> 3 (2/9) + Root 2 m/3 + 2 = 0

=> 2/3 + Root 2 m/3 + 2 = 0

=> Root 2 m/3 = - 2/3 - 2 = -8/3

=> Root 2 m = -8/3 × 3 = -8

=> m = -8/root 2

=> m = (-4 Root 2) answer.
