Factor polynomial $$ m^{2}-4 $$
Answer
$$ m^{2}-4 = ( m-2 )( m+2 ) $$
Explanation
Rewrite $ m^{2}-4 $ as:
$$ m^{2}-4 = (m)^2 - (2)^2 $$Now we can apply the difference of squares formula.
$$ I^2 - II^2 = (I - II)(I + II) $$After putting $ I = m $ and $ II = 2 $ , we have:
$$ m^{2}-4 = (m)^2 - (2)^2 = ( m-2 ) ( m+2 ) $$This page was created using
