Factor polynomial $$ 36x^{2}-121 $$
Answer
$$ 36x^{2}-121 = ( 6x-11 )( 6x+11 ) $$
Explanation
Rewrite $ 36x^{2}-121 $ as:
$$ 36x^{2}-121 = (6x)^2 - (11)^2 $$Now we can apply the difference of squares formula.
$$ I^2 - II^2 = (I - II)(I + II) $$After putting $ I = 6x $ and $ II = 11 $ , we have:
$$ 36x^{2}-121 = (6x)^2 - (11)^2 = ( 6x-11 ) ( 6x+11 ) $$This page was created using
