Factor polynomial $$ x^{2}-625 $$
Answer
$$ x^{2}-625 = ( x-25 )( x+25 ) $$
Explanation
Rewrite $ x^{2}-625 $ as:
$$ x^{2}-625 = (x)^2 - (25)^2 $$Now we can apply the difference of squares formula.
$$ I^2 - II^2 = (I - II)(I + II) $$After putting $ I = x $ and $ II = 25 $ , we have:
$$ x^{2}-625 = (x)^2 - (25)^2 = ( x-25 ) ( x+25 ) $$This page was created using
