Question

4 Simplify.
(i) (3x - 2)2 + (3x + 2)2
​

Answer 1

$\sf \: (i) (3x - 2) {}^{2} + (3x + 2) {}^{2}$

$\sf\tt\large{\green {\underline {\underline{⚘\;solution:}}}}$

$\sf \: (3x - 2) {}^{2} + (3x + 2) {}^{2}$

$\sf \: = 9x {}^{2} + 4 + 12x - 9x {}^{2} - 4 + 12x$

$\sf \: = \cancel 9x {}^{2} + \cancel4 + 12x - \cancel9x {}^{2} - \cancel4 + 12x$

$\pink{ \sf \bold{ = 24x}}$

Hence This is Answer.
