Question

What is the sum of 2x^2 and 2x^3

Answer 1

For this case we have the following expression:

`2x ^ 2 + 2x ^ 3`

The terms are not similar, so they cannot be added.

Examples of similar terms:

`x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4`

Then, the expression given can only be rewritten as:

`2 (x ^ 2 + x ^ 3)`

This is taking common factor 2 to both terms.

Answer:

`2 (x ^ 2 + x ^ 3)`
