Please I'm in urgent need of help. what must be added to make (1/4)x^2-(2/3)xy a perfect square?.​
Ipatiy [6.2K]

Answer:

\bigg(\frac{2}{3}  {y} \bigg)^{2}

STEP BY STEP EXPLANATION

\frac{1}{4}  {x}^{2}  -  \bigg( \frac{2}{3}  \bigg)xy \\  \\  =   \bigg(\frac{1}{2}  {x} \bigg)^{2}  - 2. \bigg(\frac{1}{2}  {x} \bigg)\bigg( \frac{2}{3} y \bigg ) +  \bigg(\frac{2}{3}  {y} \bigg)^{2} \\  \\  = \bigg(\frac{1}{2}  {x}  -  \frac{2}{3} y\bigg)^{2}  \\

To make \red{\bold{\frac{1}{4}  {x}^{2}  -  \bigg( \frac{2}{3}  \bigg)xy}} a perfect square we should add \purple{\bold{\bigg(\frac{2}{3}  {y} \bigg)^{2}}}
