Answer 1

Answer:

• The answer is

: : m = n = 2 = hence proved

Step-by-step explanation:

Let f = ( x ) = nx2 -5x + m

x - 2 and x - 1/2 are factors of f ( x ) then x = 2

and x = 1 are roots of

____

2

equation f ( x )

Now , we know =

product of roots = m = ( 2 ) ×( 1 )

___ ( 2 )

n

:: m = 1

___

n

:: m = n

and

sum of roots = - ( - 5 ) = 2 + 1 = 5

___ ___

2 2

:: 5 = 5 :: n = 2

__ __

n 2

:: m = 2 = hence proved
