Question

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

Answer 1

By subtracting the given addend to the sum, we see that the other addend is:

$6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8$

How to get the other addend?

We know that the sum of two polynomials is:

$8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9$

One of the addends is:

$2d^5 - c^3d^2 + 8cd^4 + 1$

To get the other addend, we can subtract the given addend to the sum:

$8d^5 - 3c^3d^2 + 5c^2d^3 - 4cd^4 + 9 - (2d^5 - c^3d^2 + 8cd^4 + 1)\\\\6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8$

Then we can conclude that the other addend is:

$6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8$
