.
Step-by-step explanation:
To solve this problem, we need to simplify the expression .
We know that
Therefore:
.
Answer:
See below
Step-by-step explanation:
x(x-2y)-(y-x)2
Final result :
-y2
Step by step solution :
Step 1 :
Equation at the end of step 1 :
x • (x - 2y) - (y - x)2
Step 2 :
2.1 Evaluate : (y-x)2 = y2-2xy+x2
Final result :
-y2
A = -11
B= -12
This is because of how calculations work in negatives. Because they are both negative they work similarly to addition
