Answer:
0
Step-by-step explanation:
=a^2/a-b+b^2/b-a
=here denominator which divides a^2 and b^2 gets cancelled
=a-b+b-a
=+a-a and +b -b gets cancelled
and answer is 0
Given
a² ÷ a - b + b² ÷ b - a ← perform the division calculations
= a - b + b - a ← collect like terms
= 0
addition property of equality
