Question

find the product using suitable properties 126 into - 138 + - 138 into minus 26 name the property used ​

Answer 1

126×(-138) +(-138) ×(-26) = -20976 by distributive property.

Step-by-step explanation:

Distributive property: It is used to solve expressions easily by distributing a number to the numbers given in brackets.

• The distributive property states that an expression which is given in form of

A (B + C) can be written as ;

A × (B + C) = AB + AC.

• This law is also applicable to subtraction and is expressed as,

A (B - C) = AB - AC.

This means variable A is distributed between the other two variables.

1. let's solve it first by this property:

The given question is :

126×(-138) +(-138) ×(-26)

-138(126-(26))

-138(126+26)

-138(152)

-20976

2. Let's solve it normally

-126×(-138) +(-(138)×(-26))

-17,388 + (3588)-----(as - × - = +)

-20976
