Answer:

Step-by-step explanation:
we have the expression:

We need to multiply the two terms in the first parenthesis by the two terms in the second parenthesis:

we solve each term taking into account the law of signs
(-)(-)=+
and

Answer:
The first question:
x = -1
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-x - 1 = -1 • (x + 1)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-1 = 0
Add 1 to both sides of the equation :
-x = 1
Multiply both sides of the equation by (-1) : x = -1
One solution was found :
x = -1
