Question

(x/2 - y/3)² resolva esse produto notável

Answer 1

$\large\boxed{\begin{array}{l}\sf\bigg(\dfrac{x}{2}-\dfrac{y}{3}\bigg)^2\\\sf=\bigg(\dfrac{x}{2}\bigg)^2-\diagdown\!\!\!2\cdot\bigg(\dfrac{x}{\diagdown\!\!\!2}\bigg)\cdot\bigg(\dfrac{y} {3}\bigg)+\bigg(\dfrac{y}{3}\bigg)^2\\\sf\bigg(\dfrac{x}{2}-\dfrac{y}{3}\bigg)^2=\dfrac{x^2}{4}-\dfrac{xy}{3}+\dfrac{y^2}{9}\end{array}}$
