The polynomial ky^3+3y^2-3 and 2y^3-5y+k when divided by (y-5) leave the same remainder in each case. find the value of k.

Step-by-step explanation:

According to the Remainder Theorem; when P(y) is divided by y-a, the remainder is p(a).

The first polynomial is :

When p(y) is divided by y-5, the remainder is

When the second polynomial:

is divided by y-5.

The remainder is;

The two remainders are equal;

i think da answer is

d.square root of 3
