Simplify.
4x^2+4-5x+x-2x^2+8
A: -2x^2+4x+12
B: -2x^2-4x+12
C: 2x^2+4x+12
D: 2x^2-4x+12
Combining like terms, we get:
2x^2 + 3x + 12
Therefore, the answer is C: 2x^2+4x+12.
To simplify the expression 4x^2 + 4 - 5x + x - 2x^2 + 8, you can combine like terms:
Combine the x^2 terms: 4x^2 - 2x^2 = 2x^2
Combine the x terms: -5x + x = -4x
Combine the constant terms: 4 + 8 = 12
Therefore, the simplified expression is 2x^2 - 4x + 12.
So the correct answer is D: 2x^2 - 4x + 12.
