The factors of the given expression [tex]144-49x^{2}[/tex] will be [tex](7x+12)(7x-12)[/tex]
It is given that
[tex]144-49x^{2}[/tex]
Now by simplifying it
[tex](12)^{2} -(7x)^{2}[/tex]
Now from the formula, we know
[tex]a^{2} -b^{2} = (a+b)(a-b)[/tex]
So it will become
[tex](12)^{2} -(7x)^{2}= (12-7x)(12+7x)[/tex]
Thus the factors of the given expression [tex]144-49x^{2}[/tex] will be (7x+12)(7x-12)
