Answer:
The answer would be x^2 - 6x - 6.
Explanation:
Let's simplify this equation step-by-step.
First, distribute the negative sign:
= x2 − 3x + 1 + − 1 (x + 2x + 7)
= x2 + − 3x + 1 + − 1x + − 1 (2x) + (− 1) (7)
= x2 + − 3x + 1 + − x + − 2x + − 7
Next, combine like terms:
= x2 + − 3x + 1 + − x + − 2x + − 7
= (x2) + (− 3x + − x + − 2x) + (1 + − 7)
= x2 + − 6x + − 6
Therefor, your answer would be x2 − 6x − 6
Hope this helps!
