The first expression can be simplified to 3bm-bn and the second expression can be simplified to m²-1.
The distributive property is a fundamental property of algebra that allows you to simplify expressions by distributing or multiplying a value to each term within parentheses. The property is commonly stated as:
a(b + c) = ab + ac
1. b ( 3m - n )
distribute the terms:
3bm - bn
The FOIL method is a useful technique when multiplying binomials and simplifying expressions. The property is commonly stated as:
(a + b)(c + d) = (ac) + (ad) + (bc) + (bd)
2. (m - 1)(m + 1)
FOIL the expression:
m²-1m+1m-1
combine the like terms:
m²-1

The correct question is:-
