The product of (a + b)(a − b) is a2 − b2. (1 point) Sometimes Always Never
jenyasd209 [6]
ANSWER

\boxed{Always}
EXPLANATION


The given product is

( a - b)(a + b)

This is always equal to

{a}^{2}  -  {b}^{2}


The identity

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


is called difference of two squares.


We can verify this by simply expanding the brackets using the distributive property to obtain,


( a - b)(a + b) =  a(a + b) - b(a + b)



( a - b)(a + b) =  {a}^{2}   + ab - ab-  {b}^{2}

This simplifies to

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