Question

2ab + (8a + 9a) =
2xy + (7x) (-2xy) =
2x + (4x * (3x) =
4xy + (6x) (-3x) =
3xy + (-7x) * (-5x) =

Answer 1

2ab + ( 8a + 9a ) = 2ab + 8a + 9a = 2ab + 17a = a ( 2b + 17 )

2xy + ( 7x ) ( - 2xy ) = 2xy - 14x ² y = 2xy ( 1 - 7x )

2x + ( 4x * 3x ) = 2x + 12x ² = 2x ( 1 + 6x )

4xy + ( 6x ) ( -3x ) = 4xy - 18x ² = 2x ( 2y - 9x )

3xy + ( -7x ) * ( -5x ) = 3xy + 35x ² = x ( 3y + 35x )

Answer 2

2ab + (8a + 9a) = 2ab + 8a + 9a == 2ab + 17a = a(2b + 17)

2xy + (7x) (-2xy) =
= 2xy - 14x²y = 2xy(1 - 7x)

2x + (4x * (3x) =
= 2x + 12x² = 2x(1 + 6x)

4xy + (6x) (-3x) =
= 4xy - 18x² = 2x(2y - 9x)

3xy + (-7x) * (-5x) =
= 3xy + 35x² = x(3y + 35x)
