Answer:

[tex]( a+ 12)(a - 12)[/tex]

Step-by-step explanation:

[tex] {a}^{2} - 144[/tex]

[tex] {a}^{2} - {12}^{2} [/tex]

Since both terms are perfect squares, factor using the difference of squares formula,

[tex] {a}^{2} - {b}^{2} = ( a+b )(a - b)[/tex]

where a=a and b=12.

[tex](a+ 12)(a - 12)[/tex]

Hope it is helpful....
