Hi ,
Plz check the first term , it may be
3x³ ,
It is given that ,
P( x ) = 3x³ + kx² + 5x - 16
If P( x ) divided by ( x - 2 ) the
remainder is p ( 2 ) .
According to the problem given ,
Remainder = 8
P( 2 ) = 8
3( 2)³ + k( 2² ) + 5 ( 2 ) -16 = 8
24 + 4k + 10 - 16 = 8
18 + 4k = 8
4k = 8 - 18
k = - 10/4
k = - 5/2
I hope this helps you.
