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