Answer:
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
