Factor polynomial $$ 49x^{2}-84xy+36y^{2} $$
Answer
$$ 49x^{2}-84xy+36y^{2} = (7x-6y)(7x-6y) $$
Explanation
Note that the polynomial $ 49x^2-84xy+36y^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 = 7x } $ and $ \color{red}{ B = 6y } $ so,
$$ 49x^2-84xy+36y^2 = ( \color{blue}{ 7x } - \color{red}{ 6y } )^2 $$This page was created using
