Question

the polynomial (kx)3 + (3x)2 - 8 and (3x)3 - 5x + k are divided by x+2 if the remainder in each case is the same find the value of k

Answer 1

There are two various methods to solve this problem. 1 st is log division and 2nd method is described as follow x+2=0 x= - 2 put the values of x in place of x that is - 2

Answer 2

Your question seems to be wrong. Please check if it is kx^3+3x^2-8 and 3x^3-5x+k instead of
(kx)3 + (3x)2 - 8 and (3x)3 - 5x + k
