Answer 1

Answer:

(a2 + ab + c2) - (a2 - d2 )

= a2 + ab + c2 - a2 + d2

= a2 - a2 + ab + c2 + d2

= ab + c2 + d2

Step-by-step explanation:

hope this helps you ☺️

Answer 2

Step-by-step explanation:

=a^2+ab+c^2-(a^2-d^2)

=a^2+ab+c^2-a^2+d^2

=a^2-a^2+c^2+d^2+ab

=ab+c^2+d^2

If it is addition, then

=a^2+ab+c^2+a^2-d^2

=2a^2+c^2-d^2+ab

I hope this is helpful.
