Factor polynomial $$ 25x^{2}+80xy+64y^{2} $$
Answer
$$ 25x^{2}+80xy+64y^{2} = (5x+8y)(5x+8y) $$
Explanation
Note that the polynomial $ 25x^2+80xy+64y^2 $ is a perfect square trinomial, so we will use the following formula.
$$ A^2 + 2AB + B^2 = (A + B)^2 $$In this example we have $ \color{blue}{ A = 5x } $ and $ \color{red}{ B = 8y } $ so,
$$ 25x^2+80xy+64y^2 = ( \color{blue}{ 5x } + \color{red}{ 8y } )^2 $$This page was created using
