Answer 2

Answer:

1 ) ( 8a + 3b )²

by using formula [ ( a + b )² = a² + b² + 2ab ]

==> ( 8a )² + ( 3b )² + 2 x 8a x 3b

==> 64a² + 9b² + 48ab

2) ( 7x + 2y )²

by using formula [ ( a + b )² = a² + b² + 2ab ]

==> ( 7x )² + ( 2y )² + 2 X 7x X 2y

==> 49x² + 4y² + 28xy

3) ( 5x + 11 )²

by using formula [ ( a + b )² = a² + b² + 2ab ]

==> ( 5x )² + ( 11 )² + 2 X 5x X 11

==> 25x² + 121 + 110x
