As ( x + 2 ) divides the given equation without leaving any remainder,
( x + 2 ) = 0
x = -2
Hence,
=> 2(-2)³ - h(-2)² + 5(-2) + 9 = 0
=> -16 - 4h - 10 + 9 = 0
=> -17 -4h = 0
=> -17/4 = h
( x + 2 ) = 0
x = -2
Hence,
=> 2(-2)³ - h(-2)² + 5(-2) + 9 = 0
=> -16 - 4h - 10 + 9 = 0
=> -17 -4h = 0
=> -17/4 = h

I am also getting the same answer that is -17 by 4 but when we divide f of X by X + 2 then it is not coming zero
Put the correct values and try once again
tried a lot
it's in vain
