Factor polynomial $$ 343m^{3}+64n^{3} $$
Answer
$$ 343m^{3}+64n^{3} = (7m+4n)(49m^{2}-28mn+16n^{2}) $$
Explanation
To factor $ 343m^{3}+64n^{3} $ we can use sum of cubes formula:
$$ I^3 + II^3 = (I + II) (I^2 - I \cdot II + II^2)$$After putting $ I = 7m $ and $ II = 4n $ , we have:
$$ 343m^{3}+64n^{3} = ( 7m+4n ) ( 49m^{2}-28mn+16n^{2} ) $$This page was created using
