Answer

-3x - 6 Explanation 1. Remove parentheses (3x^2 + 2x - 5) + (-3x^2 + x - 2) - (-1 + 6x) becomes 3x^2 + 2x - 5 - 3x^2 + x - 2 + 1 - 6x. 2. Combine like terms 3x^2 - 3x^2 = 0, 2x + x - 6x = -3x, -5 - 2 + 1 = -6.

Explanation

1. Remove parentheses<br /> $(3x^2 + 2x - 5) + (-3x^2 + x - 2) - (-1 + 6x)$ becomes $3x^2 + 2x - 5 - 3x^2 + x - 2 + 1 - 6x$.<br />2. Combine like terms<br /> $3x^2 - 3x^2 = 0$, $2x + x - 6x = -3x$, $-5 - 2 + 1 = -6$.
