Use foil to explain how to find the product of (a + b)(a − b). then describe a shortcut that you could use to get this product without using foil

The product of (a+b)(a-b)  is

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

combine like terms

The product of (a+b)(a-b)  is

Shortcut is we apply an identity

(a - b)(a + b)   =  a² -  b²

FOIL is an acronym for First, Outside, Inside, and Last

This method allows to find the product in the order First, Outside, Inside, and Last.

For the product (a + b)(a - b, using the FOIL method:

First: a(a)  = a²

Outside: a(-b)  =  -ab

Inside: b(a)   =  ab

Last:  b(-b)  =   -b²

Adding all the terms together, the expression becomes:

a²  -  ab  +  ab  +  b²

After simplification, the expression becomes:

a²  -  b²

A shortcut for finding the product is the difference of two squares

Using the difference of two squares rule:

(a  - b)(a + b)   =  a²  -  b²

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
