= a ( b + 3 ) + 2 ( b + 3 )

= ab + 3a + 2b + 6

= a ( b + 3 ) + 2 ( b + 3 )

= ab + 3a + 2b + 3

= x ( 3x + 5 ) + 1( 3x + 5 )

= 3x² + 5x + 3x + 5

= 3x² + 8x + 5

= x ( 3x + 5 ) + 1( 3x + 5 )

= 3x² + 5x + x + 5

= 3x² + 6x + 5

= p (3p + q ) - 2 (3p + q )

= 3p² + pq - 6p - 2q

= p (3p + q ) + 2 (3p + q )

= 3p² + pq + 6p - 2q

=w (w + 1 ) + w(w + 1 )

=w² + w + 2w + 2

= w² + 3w + 6

=w (w + 1 ) + 2(w + 1 )

=w² + w + 2w + 2

= w² + 3w + 2

= (r - 2s)2

= 2r - 4s

= (r - 2s) ( r - 2s )

= r (r - 2s ) - 2s (r - 2s )

= r² - 4sr + 4s²

=3u(2u + 3) + 1(2u + 3)

= 6u² + 9u + 2u + 3

= 6u² + 11u + 3

=3u(2u + 3) - 1(2u + 3)

= 6u² + 9u - 2u -3

= 6u² + 7u - 3

= -2x(-p - 4) + 1(p - 4)

= 2xp + 8x + p - 4

= -2x(-p - 4) - 1(p - 4)

= 2xp + 8x - p + 4

= ( x + 6)( x + 6)

= x( x + 6) + 6( x + 6)

= x² + 12x + 36

=( x + 6) 2

= 2x + 12

=( y - 7 ) ( y - 7 )

= y ( y - 7 ) - 7( y - 7 )

= y² - 14x + 49

=( y - 7 ) 2

= 2y - 14

=2d (9m - d) + (9m - d)

=18dm - 2d² + 9m - d

=2d (9m - d) + 8(9m - d)

=18dm - 2d² + 72m - 8d
