Answer 1

[AI-generated answer — Bot GPT 3.5]

To simplify the expression, we can start by multiplying -2 by each term inside the parentheses:

-2(x/2 - 7) = -2 * (x/2) -2 * (-7) = -x - (-14) = -x + 14

Therefore, the expression becomes:

(-x + 14)(x + 6) + 3x

Expanding the expression using distributive property:

= -x(x + 6) + 14(x + 6) + 3x

= -x^2 - 6x + 14x + 84 + 3x

Combining like terms:

= -x^2 + 11x + 84 + 3x

= -x^2 + 14x + 84
