Question

For what values of m and n, the roots of equation mx²+7x+n=0 are 2/3 and -3​

Answer 1

Answer:

m= 3 and n= -6

Step-by-step explanation:

mx^2+7x+n=0

Put x=2/3

4/9 m + 14/3 + n = 0

4m+42+9n=0......(i)

Put x= -3

9m + (-21) + n = 0

9m-21+n=0........(ii)

Solve (i) and (ii),

m= 3 and n= -6
