Answer 2

Answer:

$( \frac{1}{2} a - 3b)(3b + \frac{1}{2} a)( \frac{1}{4} {a}^{2} + 9 {b}^{2} )$

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

using the formula: (a-b)(a+b) = a²- b²

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

$= (\frac{1}{4} {a}^{2} - 9 {b}^{2} )(\frac{1}{4} {a}^{2} + 9 {b}^{2} )$

again using same formula,

$= ( { \frac{1}{4} {a}^{2} })^{2} - {(9 {b}^{2} })^{2}$

$= \frac{1}{16} {a}^{4} - 81 {b}^{4}$
