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

To simplify the given expression, we collect like terms. The expression is:

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

We can group the terms with the same power of x together:

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

Simplifying further:

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

Which gives us:

x^2 + 16x + 1

Thus, the simplified form of the given expression is x^2 + 16x + 1.
