What is a Polynomial?

The polynomial is an expression made up of indeterminates and coefficients, that involves the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Simplifying;

1. 6g + 8k – 9g + 2k = -3g +10k.              (option B)

2. –4x + 6x2 + 5x  = 6x2+x                      (option D)

3. a2 + 5a – 3a2 = -2a2+5a                     (option B)

4. 3x2 + 8x + 7x = 3x2 + 15x                     (option A)

5. The degree of –5w3 – 4w2 + 7w + 16 is 3  (option D)
