Question

Simplify: 8x3 – 2x2 + x + 3x3
A. 10x3
B. 11x3– 2x2+ x
C. 11x6– 2x2+ x
D. 8x3– 2x2+ x + 3x3 (the expression cannot be simplified)

Answer 1

B) 11x3 - 2x2 + x 

Why? because the equation (8x3 – 2x2 + x + 3x3) is equivalent to the equation of  (11x3– 2x2+ x) which they both equal the sum of (=29 + x) 

Hope this helps! 
Have a great day.
