Question

Simplify
using identity​

Answer 1

Step-by-step explanation:

using identity

(a-b)²= a²+ b² - 2ab

$( \frac{3x}{2} - \frac{4y}{3} ) ^{2} \\ = ( { \frac{3x}{2}) }^{2} + { (\frac{4y}{3} )}^{2} - 2( \frac{3x}{2} )( \frac{4y}{2}) \\ = ( { \frac{9x}{4}) } + (\frac{16y}{9} ) - 24xy \\ = { \frac{9x}{4} } + \frac{16y}{9} - 24xy \\ ans$

9x/4 + 16y/9 -24xy
