( 3x + 2y )² = 14²
9x² + 4y² + 12 xy = 196
9x² + 4y² + 12*8 = 196
9x²+ 4y² = 196 -96
= 100.
Hope this may help you...

(3x + 2y)² = 14²
⇒ 9x² + 4y² + 12xy = 196
⇒ 9x² + 4y² + 12 × 8 =196
⇒ 9x² + 4y² = 196 - 96
⇒ 9x² + 4y² = 100
⇒ 9x² + 4y² + 12xy = 196
⇒ 9x² + 4y² + 12 × 8 =196
⇒ 9x² + 4y² = 196 - 96
⇒ 9x² + 4y² = 100
