Answer 1

Question:

Verify that : ( 11pq + 4q )² - ( 11pq - 4q )² = 176 pq²

Formula to be applied:

☆ a² - b² = ( a + b )( a - b )

Here:

( 11pq + 4q ) = a

( 11pq - 4q ) = b

Answer:

= ( 11pq + 4q )² - ( 11pq - 4q )²

= ( 11pq + 4q + 11pq - 4q )( 11pq + 4q - 11pq + 4q )

= ( 22pq )( 8q ) = 176pq²

Now:

( 11pq + 4q )² - ( 11pq - 4q )² = 176 pq²

Hence verified✔
