Answer:
\((12+7x)(12-7x)\)
Step-by-step explanation:
\(144-49x^2\)
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
\(144-49x^2\)
\(12^2-7^2x^2\)
\(12^2-(7x)^2\)
Now apply difference of squares formula
\(a^2 - b^2= (a+b)(a-b)\)
\(12^2 - (7x)^2= (12+7x)(12-7x)\)
