Answer:
[tex](12+7x)(12-7x)[/tex]
Step-by-step explanation:
[tex]144-49x^2[/tex]
HEre we have 2 terms and also we have x^2
So we try to write this in square form
144 can be written as 12 times 12 = 12^2
49 can be written as 7 times 7 = 7^2
[tex]144-49x^2[/tex]
[tex]12^2-7^2x^2[/tex]
[tex]12^2-(7x)^2[/tex]
Now apply difference of squares formula
[tex]a^2 - b^2= (a+b)(a-b)[/tex]
[tex]12^2 - (7x)^2= (12+7x)(12-7x)[/tex]
