The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.

Answer:
-3
Step-by-step explanation:
-11b + 7 = 40
Subtract both sides by 7.
-11b = 33
Divide both sides by -11.
b = -3
For this case we must indicate the factors of the following expression:

To factor we must find two numbers that when multiplied result in -20 and when added, result in -12.
There are no two numbers that meet this condition. Thus, the expression is not factorizable with rational numbers.
Answer:
The expression is not factorizable with rational numbers.
Answer:
(a+2)
Soo you could solve by removing the parenthesis, then combining all like terms. Then subtract.
