To use the Distributive Property and simplify the expression \( 2(x^2 - x) + 6x - 3 - 7x \), follow these steps:
-
Distribute the \(2\) into the first term: \[ 2(x^2 - x) = 2x^2 - 2x \]
-
Now, substitute it back into the expression: \[ 2x^2 - 2x + 6x - 3 - 7x \]
-
Combine like terms. First, combine the \(x\) terms: \[ -2x + 6x - 7x = -3x \]
-
Now rewrite the expression, combining everything: \[ 2x^2 - 3x - 3 \]
Thus, the simplified expression is: \[ \boxed{2x^2 - 3x - 3} \]
