The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend? 6d5 – 2c3d2 + 5c2d3 – 12cd4 + 8 6d5 – 4c3d2 + 3c2d3 – 4cd4 + 8 6d5 – 4c3d2 + 5c2d3 – 12cd4 + 8 6d5 – 2c3d2 – 3c2d3 – 4cd4 + 8

Answer 1

The other addend is 6d5 – 2c3d2 + 5c2d3 – 12cd4 + 8.

To verify this, you can simply add the given addend (2d5 – c3d2 + 8cd4 + 1) to this potential addend and see if it equals the original sum (8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9).
