Factor polynomial $$ 49m^{2}-169 $$
Answer
$$ 49m^{2}-169 = ( 7m-13 )( 7m+13 ) $$
Explanation
Rewrite $ 49m^{2}-169 $ as:
$$ 49m^{2}-169 = (7m)^2 - (13)^2 $$Now we can apply the difference of squares formula.
$$ I^2 - II^2 = (I - II)(I + II) $$After putting $ I = 7m $ and $ II = 13 $ , we have:
$$ 49m^{2}-169 = (7m)^2 - (13)^2 = ( 7m-13 ) ( 7m+13 ) $$This page was created using
