Answer 1

$\: \: \: \:$

$= {a}^{2} \: {b}^{2} - {b}^{2} \: {c}^{2}$

Step-by-step explanation:

$(ab + bc)(ab - bc)$

• use ( a + b ) ( a + b ) = a² - b² to simply the product

$(ab {)}^{2} - (bc {)}^{2}$

• to raise a product to a power ,raise each factor to that power

$= {a}^{2} {b}^{2} - {b}^{2} {c}^{2}$
