Question

((3a)/(2b) - (2b)/(3a)) ^ 2 expand​

Answer 1

$\begin{gathered}{\Huge{\textsf{\textbf{\underline{\underline{\purple{Answer:}}}}}}}\end{gathered}$

=> 3a/2b-2b/3a²

=> (a-b)²

=> a²+b²-2ab

=> (3a/2b)²+(2b/3a)²-2(3a/2b*2b/3a)

=> 9a²/4b²+4b²/9a²

=> -2

Answer 2

Answer:

Step-by-step explanation:

((3a)/(2b) - (2b)/(3a)) ^ 2

$(\frac{3a}{2b} - \frac{2b}{3a} )^{2} \\\\= (\frac{(3a)^2- (2b)^2}{6ab} )^{2} \\\\=\frac{(9a^2-4b^2)^{2} }{36a^2b^2}$
