For this case you must simplify the expression respecting the rules of multiplication of mathematics.
The steps to simplify the expression are the following:
First multiply what is in the parentheses
-2x ^ 2 (x - 5) + x (2x ^ 2 - 10x) + x
-2x ^ 3 + 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
Then add the terms that have the same exponent
(-2x ^ 3 + 2x ^ 3) + (10x ^ 2 - 10x ^ 2) + x
x
The final simplification is
x
answer
x
5x-7x=-8
-2x=8
x=-4
this is how to solve it
Answer:
12 less than or equal to 2
Step-by-step explanation:
X^2 = 1994
x= + - sqrt (1994)
Unfortunately, there is no integer that can suit x.
