Factorization by taking common

y + y + y =

• 3y
• 3 + y
• y + 3
• y/3

2x + 2x =

• x + 4
• 2 + x
• 2 + 2
• 4x

2x + y = 1

• coeffiecient
• term
• variable
• constant

Expand and simplify:

3a (2a - 4a²b)

• 6a² - 4a²b

• 6a² - 12a³b

• 3a2a - 12a²b

• 6a - 4a²b

Simplify the expression (x+3)(x-3).

• x² - 6

• x²- 9

• x² + 9

• x² + 3
