Factoring and Expanding Expressions

Factor Completely (Using a negative factor):

-9u - 81

• 9(u + 9)

• -9(u - 9)

• -9(u + 9)

• -90u

Factor -8x - 10 (Using a negative factor)

• -4(2x - 3)

• -2(4x + 5)

• -2(4x - 5) 

• -4(2x + 3)

Factor
16x + 24x²

• 4x(2x + 6)

• 8x(2 + 3x)

Factor completley: 12x + 8y - 4z

• 4( x + y + z)

• 4 ( 3x - 2y + z)

• 2 ( 6x + 4y -2z)

• 4 ( 3x + 2y - z)

Simplify the expression:
5(p - 6)

• 5p - 30

• 5p - 5

• p - 30

• 5p + 11

8(x+5)

• 8x+40

• 8x+5

• 8x+13

2(2x + 1) =

• 4x + 1

• 2x + 2

• 5x

• 4x + 2

2(x + 3) + 4 =

• 2x + 6 + 4

• 2x + 6

• 2x + 10

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

• 5x + 5

• x + 1

• 5x + 1

Expand -2(x-2)

• -2x+4

• 2x-4
