Evaluate
A2−B2−(A+B)(A−B)
Subtract the terms
More Steps
Evaluate
A2−(A+B)(A−B)
Rewrite the expression
A2+(−A−B)(A−B)
Expand the expression
A2−A2+AB−BA+B2
The sum of two opposites equals 0
0+AB−BA+B2
Remove 0
AB−BA+B2
Subtract the terms
0+B2
Removing 0 doesn't change the value,so remove it from the expression
B2
B2−B2
Subtract the terms
0
0=0
