The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. if one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend? the choices are: a. 6d5 – 2c3d2 + 5c2d3 – 12cd4 + 8 b. 6d5 – 4c3d2 + 3c2d3 – 4cd4 + 8 c. 6d5 – 4c3d2 + 5c2d3 – 12cd4 + 8 d. 6d5 – 2c3d2 – 3c2d3 – 4cd4 + 8

The correct option is A.

Step-by-step explanation: We are given a polynomial which is a sum of other 2 polynomials.

We are given the resultant polynomial which is :

One of the polynomial which are added up is :

Let the other polynomial be 'x'

According to the question:

Solving the like terms in above equation we get:

Hence, the correct option is A.
