Answer:
([tex]a^{2}[/tex] + [tex]b^{2}[/tex])
([tex]m^{2}[/tex] - [tex]n^{2}[/tex])
Step-by-step explanation:
1. Write as an expression: the sum of the squares of a and b
It is asking to square each a and b and then add them
([tex]a^{2}[/tex] + [tex]b^{2}[/tex])
2. Write as an expression: the difference of the squares of m and n.
it is asking for square each m and n and then subtract them
([tex]m^{2}[/tex] - [tex]n^{2}[/tex])
