[tex] = {a}^{2} \: {b}^{2} - {b}^{2} \: {c}^{2} [/tex]
Step-by-step explanation:
[tex](ab + bc)(ab - bc)[/tex]
- use ( a + b ) ( a + b ) = a² - b² to simply the product
[tex](ab {)}^{2} - (bc {)}^{2} [/tex]
- to raise a product to a power ,raise each factor to that power
[tex] = {a}^{2} {b}^{2} - {b}^{2} {c}^{2} [/tex]
hope it helps
