Factor polynomial $$ 64x^{3}+125y^{3} $$
Answer
$$ 64x^{3}+125y^{3} = (4x+5y)(16x^{2}-20xy+25y^{2}) $$
Explanation
To factor $ 64x^{3}+125y^{3} $ we can use sum of cubes formula:
$$ I^3 + II^3 = (I + II) (I^2 - I \cdot II + II^2)$$After putting $ I = 4x $ and $ II = 5y $ , we have:
$$ 64x^{3}+125y^{3} = ( 4x+5y ) ( 16x^{2}-20xy+25y^{2} ) $$This page was created using
