Answer :
Given: the denominator cannot equal zero.
[tex]a^2-b^2=0\\a=b\\a^2-a^2=0[/tex]
The function [tex]\frac{a^2+ab+b^2}{a^2-b^2}[/tex] is undefined under the condition that a = b.
[tex]a^2-b^2=0\\a=b\\a^2-a^2=0[/tex]
The function [tex]\frac{a^2+ab+b^2}{a^2-b^2}[/tex] is undefined under the condition that a = b.
