To find the polynomial added to given polynomial so that it may be exactly divisible by 5 x2 – 2x – 4 we will divide 15 X5 + 19 X4 + 37 X3 - 19 X2  + 40X –25
by 5 x2 – 2x – 4  and we get remainder which is the polynomial added or subtracted to get exactly division by 5 x2 – 2x – 4 
2426/25x - 133/25 is the polynomial whioh is added to 15 X5 + 19 X4 + 37 X3 - 19 X2  + 40X –25 this so that it is exactly divisible by 
5 x2 – 2x – 4
