Question

Combine the like terms to simplify the expression:

9 + 3 + 17xy2 + 8y3 + 10x –13xy2 – 9x – 6y3
A. 2y6 + 4x2y2 + 10x + 12
B. 2y3 – 4xy2 – 3x + 12
C. 2y3 + 4xy2 + 10x + 9
D. 2y3 + 4xy2 + x + 12

Answer 1

9 + 3 + 17xy² + 8y³ + 10x - 13xy² - 9x - 6y³
rearrange like terms together
(in descending exponential order)
8y³ - 6y³ + 17xy² - 13xy² + 10x - 9x + 9 + 3
2y³ + 4xy² + x + 12

Answer is: D.2y³ + 4xy² + x + 12
