Final answer:
To factor out -1/2 - 1/2 from -1/2x + 6, multiply -1/2 by the expression inside the parentheses and distribute. Then, simplify and combine like terms to get the factored form: -3/2x - 6.
Step-by-step explanation:
To factor out -1/2 - 1/2 from -1/2x + 6, you can rewrite the expression as (-1/2) * (x + 2(6)). Then, distribute to get (-1/2)x - (1/2)(2) * (x + 2(6)). Simplify further to get (-1/2)x - x - 6. Finally, combine like terms to get (-1/2 - 1)(x) - 6. Therefore, the factored form of the expression is -3/2x - 6.
