To simplify the expression 4x^2 + 4 - 5x + x - 2x^2 + 8, we can collect like terms by combining the coefficients of the same variables.

First, let's combine the x^2 terms: 4x^2 - 2x^2 = 2x^2.

Next, let's combine the x terms: -5x + x = -4x.

Now, let's combine the constant terms: 4 + 8 = 12.

Putting it all together, the simplified expression is 2x^2 - 4x + 12.

To simplify the expression 4x^2 + 4 - 5x + x - 2x^2 + 8, you can combine like terms.

First, let's combine similar terms with the same exponent of x. We have 4x^2 - 2x^2, which equals 2x^2.

Next, let's combine the terms without an exponent of x. We have 4 + 8, which equals 12.

Finally, let's combine the terms with an exponent of x. We have -5x + x, which equals -4x.

Putting it all together, the simplified expression is: 2x^2 - 4x + 12.
