Question

2 1 x² + x x² + 3x + 2​

Answer 1

To simplify the expression, we can combine the terms with the same power of x.

First, let's combine the terms with x²:

2x² + x² = 3x²

Next, let's combine the terms with x:

x + 3x = 4x

Finally, let's combine the constant terms:

2 + 0 = 2

Now, we can put all the simplified terms together:

3x² + 4x + 2

Therefore, the simplified form of the expression 2x² + x + x² + 3x + 2 is 3x² + 4x + 2.
