Factor polynomial $$ x^{3}+8y^{3} $$
Answer
$$ x^{3}+8y^{3} = (x+2y)(x^{2}-2xy+4y^{2}) $$
Explanation
To factor $ x^{3}+8y^{3} $ we can use sum of cubes formula:
$$ I^3 + II^3 = (I + II) (I^2 - I \cdot II + II^2)$$After putting $ I = x $ and $ II = 2y $ , we have:
$$ x^{3}+8y^{3} = ( x+2y ) ( x^{2}-2xy+4y^{2} ) $$This page was created using
