on dividing x^5 + kx^2 with (x-1) (x-2) (x-3) we get the remainder (k+90)x2-239x+150
as the remainder contains no x2 terms …............k+90=0............k= -90= -10(9)
 
first exp (x-1) (x-2) (x-3) and then solve the problem , on solving/dividing make sure that all the coefficients of x2 are at same place.
i gave u remainder bcuz if u tried it u can solve 4 remainder
