Hi I need help I cant find the result. thanks

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
