16x+2+2x-15x^2-1+14x

since addition isd commutative, this is just

-15x^2 + 16x+2x+14x + 2-1
now just collect like terms

To simplify the expression 16x + 2 + 2x - 15x^2 - 1 + 14x, you can combine like terms and arrange them in descending order of exponent:

First, let's group the terms with the same variable:

(16x + 2x + 14x) + (2 - 1) - 15x^2

Combine the like terms:

32x + 1 - 15x^2

To simplify the expression 16x + 2 + 2x - 15x^2 - 1 + 14x, we need to combine like terms. Like terms are terms that have the same variable and exponent.

Step 1: Combine the x terms:
16x + 2x + 14x = 32x

Step 2: Combine the constant terms:
2 - 1 = 1

So the simplified expression becomes:
-15x^2 + 32x + 1
