Answer:
9 - 7x - x²
Step-by-step explanation:
-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²
I arranged the like terms together so it is easier to do the calculations.
-4x-3x+2x2+5-x² = -7x+4+5-x²
Simplify.
-7x+4+5-x² = 9-7x-x²

Answer:
2 positive * 1 negative = negative
2 negative * 1 positive = positive
Step-by-step explanation:
one positive and 2 negative
(+ * -) * - =
positive times negative = negative * negative = positive
(+ * -) * - = +
now if we change the order by putting parenthesis
+ *( - * -)
negative time negative = positive
+ * (+) = positive
the result is positive
The result does not change because of where we put the parentheses.
- * + * + =
negative times positive = negative
negative * positive= negative
- * + * + = negative
The order does not matter
