Answer 2

Answer:

1. a^2 - 36

2. m^2 - n^2

Step-by-step explanation:

1. ( a + 6)( a - 6)

= (a)^2 - 6^2

[ because (a^2-b^2) = ( a + b)( a -b) ]

= a^2 - 36

Hence, answer is a^2 - 36.

2. ( m + n )( m - n)

= (m)^2 - (n)^2

[ because (a^2-b^2) = ( a + b)(a - b) ]

= m^2 - n^2

Hence, answer is m^2-n^2.
