If x=-3 and x=2/3 are the
quadratic equation of mx2 + 7x + n = 0, find the values of
m and n.​

Answer 1

Answer:

If x=-3 and x=2/3 are the

quadratic equation of mx2 + 7x + n = 0, find the values of

m and n.​

Step-by-step

By using sum of roots

-3+(2/3)=-7/m

-7/3=-7/m

m=3

Now using product  of rule formula

-3*2/3=n/m

-2=n/m

n=-2m

n=-6

hence  m=3 ,n=-6
