Identify the properties used for the first two steps in simplifying 6ab2 + 4a2b – 3ab2 + 3a2b – 2a2b2.

Kryger [21]

The expression $6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2$ has two similar pairs of conjunctions.

1. Rewrite this expression as
$6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2=$
$=(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2$
and then
2. add the similar conjunctions

 $(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2=3ab^2+7a^2b-2a^2b^2$ .
