Question

Is 3x + 3x​ 2​= 6x​ 3​ ? Explain.

Answer 1

No

Explanation:

It is not, because we can only add the terms that contain x of the same order.

For x to be grouped with x 2 resulting in x 3 the terms would have to be multiplying

In this case they are grouped

x * x 2 = x 3

In this case they are not grouped

x + x 2 = x + x 2
