Solve :

$( \frac{1}{2} a - 3b) {}^{2}$

$\color {red} </p><p>\Large \underline {\underline {Using \: Identity \: :}}$

$(a - b) {}^{2} = {a}^{2} - 2ab + {b}^{2}$

$\color {red} </p><p>\Large \underline {\underline {Solution \: :}}$

$( \frac{1}{2} a - 3b) {}^{2}$

$= ( \frac{1}{2} a) {}^{2} - 2( \frac{1}{2} a)(3b) + (3b) {}^{2}$

$= \frac{1}{4} {a}^{2} - 3ab + 9 {b}^{2}$
