Answer:

The product of (a+b)(a-b)  is a^2 - b^2

Step-by-step explanation:

Use FOIL to explain how to find the product of (a + b)(a − b)

FOIL is

Multiply First terms : a*a = a^2

Multiply Outside terms : a* -b = -ab

Multiply Inner  terms : b * a= ab

Multiply last terms : b * -b = -b^2

now we combine all the terms

a^2 -ab+ab - b^2

combine like terms

a^2 - b^2

The product of (a+b)(a-b)  is a^2 - b^2

Shortcut is we apply an identity

a^2 - b^2 = (a+b)(a-b)

8)Solve and rewrite using the distributive property __(__+__) = 12 +24​
Alla [95]

The distributive property will give answer 2 ( 6 + 12 ) = 12 + 24 .

The distributive law of multiplication over basic arithmetic such as addition and subtraction is known as distributive property .

According to this property , multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the no . and then adding the products together .

In other words, according to the distributive property, an expression of the form A ( B + C ) can be solved as A ( B + C ) = AB + AC.

2 ( 6 + 12 ) = 12 + 24 .

Hence , the distributive property will give answer 2 ( 6 + 12 ) = 12 + 24 .
